I don’t what to think am I the problem?

I’ve been in a Situationship for two years with a guy and we basically lived together 98% of the time. We used to have sex. He made me believe he was to so modest. I’m beginning to realize to he’s a big freak. Our sex life is nonexistent now but he has sex with everybody else. I Don’t understand.

Maybe I need to say this…. I don't want a relationship…i do not trust men…im not asking why won't he be in a relationship with me… what im asking is what makes a man decide he doesn't want sex with someone that he has been having sex with yet still lives with but instead gets it from other people. I understand i make poor choices and those poor choice have given me a very messed up outlook on men. I get that not men aren't the same, however every man that i know has all been the same.
