Need advice

I really do miss the guy that I use to talk to. We were very close, but now is so different. One thing that I have notice that when I use to ask him about our relationship he would blame me for everything, but now when I recently ask about our relationship he started blaming himself for not letting things workout. Idk what to think anymore is like he shows me he has feelings, but then it feels like he doesn't.  I don't know :(
