Relationship Issuses

How do you get your boyfriend after a year  to be sensitive towards you? I mean it's like on and off niceness and then he can be a real asshole at times and wants to leave. He says I'm annoying and I'm too emotional . I'm trying to change that stuff about me but when I tell him about himself he never wants to talk about it . He says ok , oh, it's like it's no getting through to him . What do I do ??
