I Wish I Was Allowed To Talk About It.....

I've been with my boyfriend for about 10 months and 3 months into dating I found him texting his ex. It was about meeting up at a hotel and all sexual stuff. I confronted him and he apologized and said he never went through with it. It bothered me for months. Everytime I wanted to talk about it he would go off saying I was rubbing it in his face saying I was making him feel worse. Everytime I drive past a hotel I get this sick feeling. It eats me alive. I caught him liking facebook pages of half naked girls, he calls other girls hot, and he talks to other girls on a site like facebook/myspace. Everytime I bring it up that it bothers me he makes some kind of excuse or denys it. I'm beyong sick of it. I'm not allowed to talk about the future(kids,marriage, moving in together), his brother going to jail, or of course our problems. I dont get why he said in the beginning communication is everything and now I cant talk about anything without a fight starting or him saying I start the fights. Hes selfish and everything is always his way. When he talks about something that is bothering me he ignores me when it bothers me and he continues to do it. Sometimes I feel like he still loves his ex and hes just using me. I feel like he puts others infront of me and I dont know how much more I can take. I'm starting to build resentment because I cant talk to hi about anything that bothers me because he blows up EVERYTIME I tell him whats bothering me. Idk what to do.
