My relationship is falling apart
My boyfriend and I have been together for about six months, not a long time I know however I fell in love with him. When we first got together he told me he was bisexual. I am okay with his sexuality but now that we are in a committed relationship and talking about marriage I am having a hard time dealing with it. He left me in the middle of the night to go and meet a guy for sex, he says nothing happened but who really knows the truth. I was crushed and its something I will not forget. Also, there have been numerous messages through myspace and Facebook of him trying to hook up with guys. Over the past few months he has been really insensitive to the things he says to me... it feels like I never get compliments, only criticism. One night I walked in on him getting ready to masturbate to a picture of a guy, that was not such a big deal to me accept for the fact that my needs are not being met sexually. I want him to be romantic and make love to me but what I get from him is, "hey lets f**k"... at times he will act like he is ready to have sex and then all of a sudden he says no. I feel teased and let down. He changed the passwords to his emails and such and I feel its because he is trying to hide something from me. He is constantly calling me a ***** because I get angry with him and the way he treats me. I've tried to talk to him seriously about our relationship but he can't make it through an adult conversation. He usually ends up saying something smart or making a joke of it. Not to mention that he can never accept responsibility for his actions and everything gets turned around to be my fault. I'm not happy mentally, emotionally, or physically but I do love him and want to salvage what we first had. What do I do?
