I Think Good Communication Is Vital To A Good Relationship

I need some advice because I strongly believe this statement. I don't believe I'm happy, I broke up with my boyfriend and got back with him because I felt bad. I feel like he never listens to how I feel. I'm trying to start fresh with him but I hate when he touches me so much. I try to explain to him that I need physical space and he crystal and whines that he wants to be close to me. When I do anything I feel like he doesn't want to be involved but he complains that I never share what I like with him... but it's because he doesn't seem to care or share interest. He's a bit slobs which drives me insane and he throws little tantrums and I just don't know how to either fully end it or explain to him what I need without feeling like the bad guy. Also his family completely believes I'm the reason he's doing so well but it's such a burden yet I love his siblings so much. Ugh it's a mess but I need to know what's best for ME!
