Feel Like Punching Her Sometimes!!

Me an my H moved in w my MIL because he had too much debt and we couldn't afford our apt. We have 2.5 years living here and I've already started having symptoms to this constant stress... She is sooo nosy; she always asks where I'm goin or where I am. Since my H has social anxiety and never leaves the house unless its for work, she fumes over me leaving her baby by himself for a couple of hours and not everyday. She hates when I cook; barely eats it and always tries to take over the kitchen ( its her kitchen I know) with things like "but I cooked so much food already, why don't you leave that for some other day". Well I don't always want to eat Russian food bc I'm not Russian!!!! I go and get stuff to cook but it's a hassle to do so.
This psycho always tries to come in our room without knockin so I have to hole up in a room if I want some peace of mind. She told me the other day that she didn't understand why her kids were such a****** to her but here's why: you treat them like babies!! She believes house work is reserved for women, she gets up to make breakfast and his shake to her eldest (who's 40), she does all the laundry except for me and my H bc I think he SHOULD be doin his own laundry! She complains about all the sacrifices she makes but forgives her eldest for beating her. My BIL lives w us too and does nothing! He only complains and fights w everyone including me. He hits his mother and has gotten in my face when I have tried to stop fights bt him and my H... I pretty much hate this while family. Mental illness runs rampant and this dysfunction is killing me! I've tried talkin to my H about moving but he doesn't even try to save a pennie.. I'm unemployed (he doesn't really give me any money) , but searching and hoping to get a job soon and I'm out this crazy house!!!
And I hate my H more for knowing how she was and still movin in (we had my moms support so we could have moved into a tiny apt), and for not taking a stand against this monster. Made me realize what a p**** of a man he is and how I'm never goin to have kids w him!
Can't wait until I'm out!!! When i told my H about his brother hittin his mom he didn't really care; he just said "she's lying".. This would make her the worst mother in the world in my eyes, but who knows! Anyone could be lying! If I ever see something like this I will call 911 and she will hate me for it! She always says its not her eldest's fault; "he's just sick".. I feel like slapping her! He's just a lazy bum who got "sick" after gettin his ex pregnant n did not want to get a job to support his kid, and still doesn't. The MIL wants me to "save" my H, she believes that " if u talk to him he will want to go out".. No b****! He needs to want to get better! Sometimes she just tells at him "she's gonna leave you, you'll see!!" in front of me!!! I dream about the day I'll move out and never have to see these ppl, especially my loca MIL!!!!
