Need advice..

I've been with my bf 5 years. In the beginning everything was great between us, even with his crazy ass ex literally banging on our doors and calling all hours of the night. Over the past 2 years thing have gotten to the point where idk what to do anymore.

He constantly accuses me of lying. About where I am, what I'm doing and who I'm with. I've never given him a reason to think I was unfaithful. Hes always talking shit to me about anything and everything. We dont live together but I'm with him 5 days a week at his house. (Long story). But I have my own house, and my mother lives with me while her and my dad are separated. When I'm home I watch tv and just lounge around. But some how that's sketchy. I always answer when he textsbor calls, if I miss a call or text by like 5 minutes he automatically starts talking shit that I must be with my other man.

But if I call or text him and dont get a reply for hours and say something, he gets defensive. The minute I finally say something like I did tonight, he tells me it's out of no where. Its literally a cycle with him. Every couple of weeks he does this. He gets in moods and it's like I'm the biggest piece of shit in the world. And when I say something about how he makes me feel, "its not his fault" I feel that way.

I'm not a very sexual person, and he knew this when we first started dating. And now he just talks shit to me, in front of other people about how he doesnt get laid and that I dont love him. Which is a lie. We have sex at least 3-4 times a week sometimes more. But he turns around and accuses me of being with someone else.

I know I'm all over the place and things seem to be jumbled but theres just so much and I just cant type that much. I dont know what to do. I did have my period the past week and I do get crazy mood swings and I never take anything out on him, and if I start to, I stop and apologize. I cant control mood swings.

I'm adding some of tonight's conversation.. just to get an idea.
