I'm confused.

So I've been with my boyfriend for a year now, and when he comes over he's a good loving boyfriend, but then he's always accusing me of things that I never even did and it gets annoying! Then we he goes back home he'll text and fight with me saying I need to tell him the truth and stop hiding shit? When I'm not hiding anything at all?! But now the past 2 weeks I'd say, everytime he goes home, I seriously don't even hear from him. He'll hangout with his friends or straight up ignore me. I do love him to death, it's just I don't know what to do? Have you ever dated someone who does nothing but accuse you of things? If so, tell me about it & how everything worked out.
