I've been sleeping with this guy..

So I've been sleeping with this guy for 7 months now. In the first month or so, I said we had to figure something out, did he like me, did he just want to have sex, or if he wanted nothing else to do with me. He said he wanted nothing more than just friends. Then a couple weeks later we talked and decided we would be FWB. We have been sleeping together ever since. We never had another talk. Just recently he got mad really mad at me because I said he hated me. Later that night when I got home I texted him and told him I really liked him but I understand if he didn't feel the same. He didn't say anything about it. Then about two weeks after he blocked me on Facebook. (This was about one week ago now..) I saw him out Saturday night, I went home with him. It was different from all the other times but a good different. A really good different but I don't know how to explain it. We were very playful and talkative and even tried new things. 
I am so confused as to what all of this means! Help!
