How to break up with someone who still loves you?

My boyfriend and i just hit our one year, and i'm not happy about it at all, but my boyfriend is. The relationship is just bland to me at times now that we're in college. We can't see each other much, but when we do it's nice. His family strongly dislikes me and doesn't like us hanging out, so sometimes they interfere with plans. I love spending time with him, but I don't feel that in the long run it'll work out. When I'm away from him, I constantly think about breaking up with him, but once I'm with him I don't want to, but now I know for sure that I need to. I need tips on breaking up with someone, I'm not prepared whatsoever.
