Why doesn't he contact me, is it over?

face it it is over and go on with your life.

Maybe he's on a 'Holiday'!

You deserve better.
When they dissappear, it means they have appeared in someone elses horizon doing the same things he did with you. He lacks the balls to tell you. He will string you along as long as he can. You are his 'backup plan'. You will be as long as you let it happen. Open your eyes. Think of all the things hes done in your relationship that suck. There were many. At least as many as the good.
There are types of men out there. They are consistant, they dont change. Mens brains arent like ours. If you find a GOOD ONE, you will know it because you wont have any doubts.
One that gives you doubts, does so conciously, and for good reason.
DO NOT CONTACT HIM...find a friend who will let you email THEM the letters you would write to HIM instead and go through the process of rediscovering who you were before you had to compromise your standards in order to accept such low terms in a relationship. GRIEVE. if you ignore it, it will come GET you when you dont want it to. HES NOT WHO YOU THOUGHT HE IS...hes with someone else, doing to them, the SAME thing he did to you.
DONT be jealous of this woman. She has NO IDEA what shes walked into, and if shes decent, she will try to help him and fall for the same crap. she will wind up in tears too.

Im very sorry. But open your eyes and do nurturing things for yourself during this time, but accept its a done deal. If for no other reason, than because its not good enough for YOU. Take yourself out of that equation. its not good enough for your world.
bsides...if you take him back after, he can give you something hes contracted. he has no concious, and does NOT care about how all this makes you feel. He probably hasnt for much longer than you realize. THERE ARE GOOD MEN OUT THERE. find them. in the meantime, a very good friend is nice to have.

Do not call, write or anything like that anymore
anything more you do its like giving him all the power and lowering your self worth
if he does not call back then its done
im sorry

Either something happened to him or he is a gutless little boy. If the second is true he is not worth giving a second thought to.

He could be just busy or maybe not feeling well, I'd give it a little more time and then e-mail asking if something is wrong. I think it is better just to come out and ask so you are not left wondering forever. Good luck, hope he contacts you soon.

ok i had that same thing happen to me first week in may -after we had been seeing each other for 9 months like u we were together weekly or when ever possible and we emailed and texted, some phone conversations , when we parted with a kiss and talked together on the phone on the way home everything seemed fine and we had planned to speak to each other in a couple of days due to we both had plans for the weekend -- then nothing , just nothing from him for 9 weeks -- i was very very sad and missed him terribly, then he emailed me like nothing had happened -- at least it gave me the opportunity to ask 'uh was it something i did?' and no it wasn't but it did involve someone else -- painful

Mayber something happened to him. Can you contact his workplace to make sure he's OK?
