I'm in a similar situation that your in, my dad and your dad would be best friends. Except your dad is a little bit worse.
My dad hates my mom, but if he layed a finger on her, I'd kill him PERIOD. But my problem with you is why didn't you help your mom, because your scared of your dad?! **** that man, help your mom, get a knife and do him in or call the cops or something put his punk *** in jail. Me I would kick the **** out of him, I'm 6 foot 1 and I'm about 4 inches taller than my dad so I could kick the **** out of him. Don't let that happen again, if now you know what you have to do than help her! Don't sit in your room and listen to your dad rape your mom, What the **** were you thinking. I'm not going to call you a coward but it was your job as her son to step up and flip the script on him. I take that back, don't shoot him or kill him, call the cops and than kick the **** out of him, if you can. Now I'll say my situation.
When I was about 4 years old, I think from what I can remember, my parents were already divorced. And it was just me and my mom and my older sister. Soon when I was 5 or 6, they got back together. My dad never hit my mom but he would be aggressive in arguments. He would tell her to shut the **** up and all that, and what could I do when I was 6 years old? Nothing but just listen. They were arguing in the guest room and he closed the curtain(since that was what we had) after that I peeked my eye in the little whole and my dad through a spray can at the whole and it almost hit my eye, and my mom tried to defend me and that was that, pretty much all I remember. He didn't hit her or anything. Soon my mom divorced him and moved out and moved elsewhere, and there would be few occasions where my dad would come and bang on the door, last one I remember was when my uncle(who lives with us) supposedly twisted my little sister's lips and she went and told my dad. And at that time, like you, my dad made me think that my mom was a "witch" along with my grandma and my older sister. He talks **** about her all the time even now. He calls her everything I can think of. Back then I thought my dad was the man, I looked up to him and wanted to be just like him, when he would drop me off on sundays when I came back from sleeping over his house I used to cry. Sometimes he yelled at me when I was younger, but not to the extent at which he does now. In 2005 When I was in 7th grade, I was living with my mom and I would sleep over my dad's house during school day's and eventually, during christmas break I didn't get anything for christmas and whatever I got, weren't the things that I asked for, I was such a ******* dumbass, I can't believe I did this, I got angry and reckless and decided to move with my dad, which was the biggest mistake of my life, I gave up al the happiness that I had to live with him. And I remember my mom's words "Are you sure? Is this really what you want to do?" And I said yes and just left with all my things. I'm tearing up now because It's hurts to think that I didn't listen to my mom when she used to warn me about my dad. And it was on christmas day when I did that. IT WAS MY ******* CHRISTMAS PRESENT TO MYSELF! TO SCREW UP MY ENTIRE LIFE! AND I WOULD GIVE ANYTHING TO TAKE IT BACK AND GO BACK IN TIME AND JUST TELL MY DAD THAT I DIDN'T WANT TO LIVE WITH HIM. So that same year, my dad was normal, he didn't yell or did any of that(I had switched schools also) soon, in 2007 my dad changed, he started yelling and calling me a *****, dumbass,******* and all that. He even started hitting me then, (back then he was bigger than me). He would punch me on the head with his fists, usually one hand with the rings on it. But before all of that I ******* called my mom and teamed up with my dad and ******* yelled at her over the phone. I HATE MYSELF FOR THAT. I CALLED HER ON THE PHONE AND PATRONIZED HER WITH MY DAD, I DIDNT CURSE BUT HE DID. WITH THAT BEING DONE, I DIDNT SPEAK TO HER OR ANY OF MY SISTERS FOR AN ENTIRE YEAR. And that was before my dad started yelling and doing all of that. So during eighth grade my grades declined and that would give him a reason to yell and hit me and all of that. Eventually I failed math and earth science and went to summer school.
Towards the end of summer school, the report cards were supposed to come out and one night when we were at my aunts house he had the report card and he didn't open it until we both got into the car to leave. I was in danger of failing math in summer school and my dad flipped out. But during that time, I made sure I apoligized to my mom for what I did, but she is still sore about it now but doesn't really hold it against me. So my little sister was with us that night and he yelled at me in the car in front of her when he was on his way to drop her off at my mom's house(He was cursing, not just yelling). He let her out the car and she looked at me when she got out the car and starting tearing and waved. And I was already upset just looking at my sister, and my dad waited for her to get inside and he started punching me on my chest, and I wasn't about to fight my dad(Now I would). I was pretty scared and he said "i'm going to kick your *** when we get home" and I just remember looking at my mom's window when we were leaving which made me cry and wish I hadn't moved with my dad in the first place. When we were in the car he kept saying "all i ******* ask you to do is your school work and you can't even do that, ***** I ******* hate your ***, it's all your mother's fault, she made you like this, and you keep insisting on going to her house, dumb *** *****, I wish I could just get a gun and shoot her *** right now if it wasn't for the law.(He still says things like that now but not as extreme, because I work out now and build muscle and i'm taller and bigger than him.By the way my dad is a math teacher.)
So when we got home my dad my dad told me to put out my hand and he kept hitting me with his belt, it stung but I'm a guy, so it wasn't that bad. He threatened to do it again but he never did it again. So now he continues to yell and patronize me but the worst he really did was punch me on my head and shoulder. Later, I ended up going to summer school later on, and I failed math(now i'm repeating the class) and my cousin(who is my best friend) and his family were at my house that night, he had the progress report and read it before he went in my room. My cousins were downstairs and I was playing super smash bros brawl. He came in and showed me the progress report,and he was kind of whispering because my aunt was in the room talking to his girlfriend(who had a baby, who is a boy). He kicked the chair I was sitting on and my aunt heard the loud bang and she yelling "HEYY" and she came out and my dad tried to close the door but she came in anyway and then she pulled me away from my dad and he tried to smack me on my head. And by the way, he always pretends to be cool around other family members and other people but when he's home it's different. And i'll never forget this, my cousin(my best friend) came upstairs and then when he saw what was happening he went back downstairs like nothing was going on, and it really hurt me because if he was in that situation I would help him.(this was when I was 9th grade going on tenth.) so after that he came in the room and started talking down to me in front of his girlfriend and my aunt, and they didn't really defend me, my aunt I was expecting to defend me but she really didn't say much. He called me a ***** and all that. I left that night and stayed at my aunts house for a couple of days and then she sent me back. But he was mellow after that and didn't really say anything.
My motto is, no matter how nice he pretends to be, it's only a matter of time before he get pissed off again. And my self-esteem only gets lower and lower when he yells and calls me curse words and names.
Soon in 2008, I got myself a dog.(My dad bought it) It was a Doberman-Black Lab Mix, I called him Roscoe because I'm a emotional guy and I'm into disney movies and there was a Doberman named Roscoe in the movie. My dad didn't like the dog, when his friends came over he would pretend to pet the dog, Roscoe was a frisky dog, and he would bark a lot. He my would smoke around him and blow smoke in his face. I FEEL LIKE KILLING HIM JUST FOR THAT THOUGHT. Sometimes to scare him, he would put his cigarette next to Roscoe face to make him move back. He never let the dog roam the house,the dog would be outside for more than half the day, and he would abuse the dog(Rarely) he would hit it on it's rear end(a dog's sensitive area,painful if hit there) on purpose. He would yell "SIT" at the dog when he didn't bring him to training to learn all of that. Before my cousin(my best friend) got a dog and got hit by a car and got a punctured lung and died the day before halloween. Soon after they took my dog away because my dad put him outside in the rain and I guess he was barking. I didn't get to say goodbye to my dog, and that night I was out with my mom(I go every weekend). My dog is generally aggressive with strangers(partly because of my dad) so when one of my dad's friends reaches out to him, he would usually show his fangs and lung out to bite. But he wasn't like that with other people, he was very selective. So he could've been biting them, they may have euthanized him. I don't know, I would rather go on with the thought that he is in a better home.
So in december 2008, the day before christmas break started, well, before that, my dad threatened to kill me, so I got worried and I told my guidance counselor, but she wasn't suprised because I told her about my dad since september. One word of advice, TALK TO YOUR GUIDANCE COUNSELOR. IT'S A BIG WEIGHT OF YOUR BACK! IT'LL HELP YOU AND YOUR MOM! DON'T STAY IN THAT SITUATION ANY LONGER! STOP BEIGN SELFISH! HELP YOUR MOM! It took me a while to open up to her, but I remember i started crying in the middle of a conversation with her. She gives me advice usually, kind of like therapy. So anyway, I told her what my dad had said, and soon after she told a child protective services lady, and it was this whole cherade, I missed all my classes, I spoke to an officer, another woman, the school psychiatrist and eventually, my older sister came back from college and the social worker told her to come pick me up. She did but I had to get my things from my dad's and she was going to call him and go to his house. Fortunately I went to my house earlier and I was already out. I WAS TOLD NOT TO GO TO MY DAD'S HOUSE! Later that night, we went to chili's with my sister's friend but I was worried from the get go because people were calling my phone and my dad was constantly leaving messages. So I turned it off, after we left chili's I was in the car with my older sister, my little sister, and my older sister's friend. And I listened to my dad's message, and he said " I better bring my *** home". My mom was away at the time, she was at a meeting in another state, and my older sister called her, and my mom didn't seem to care. So she told my sister to bring me home because she didn't want my dad showing up at her door.
So later on my sister dropped off her friend and was going to drop me off. Soon my older sister and little sister break down and start crying because it was too much for them. I show up at my dad's and then my sisters are still crying and i'm still scared because my dad was furious. So later I call my friend who has been through a similar situation and he didn't know what to do, because it's a touchy situation, he knew about my dad already.(I don't tell my friends about my problems unless they are close friends). So later I call my uncle and I tell him the situation and I asked him to pick me up, he said he would call my dad and and talk to him. And he did and my dad was acting like nothing was going on. So later I ask to speak to my dad as a alternative from keeping quiet. Before when i tried telling him how I'm feeling he didn't listen and flipped the script. He flipped the script and yelled at me. He doesn't hit me but I just go and cry myself to sleep.
The next day my dad gets called to the social services place and he picks up my cousin's mom and then they are both yelling at me. my dad asked me "WHAT DID YOU WANT TO HAPPEN?!! WHATEVER IT IS, IT'S NOT GOING TO WORK!" WE get to the social services place and we sit down in a small room and i'm already about to start crying so she asks to remove me from the room. I call my friend and I break down over the phone. And he helped me through it, until I go in after my dad and my aunt leave. I tell her the situation and we call my mom and my mom doesn't want to deal with my dad so she doesn't step up and ask for custody and then she hangs up on me. I remember just sitting there with the phone hoping that she would pick up, but she didn't. I FULLY break down and I punch a hole in the wall. My aunt(my best friends mom) hugs me and all that and she starts crying. And my dad doesn't say anything. I stay at my aunt's house for three days until christmas and then she tells me that I have to go back. And I don't say anything to my dad for weeks. Things get back to normal and even now he still keeps yelling and I still see my mom.
More things have happend but that would be too much. So yeah I think your situation is a little bit worse than mine.
