Guy's Behavior

Called out a guy, then why he blocked me now?

I met this guy through dating online and chatted for sometime. We asked each other some things and answered openly, including questions related to sex things. I asked him once if he was only interested in sex things with me, he said no, he did care for me too.
I like this guy and he liked me too. But in the middle time, the text only became sexual, it seems like he only wanted sex things from me. It’s frustrating because he then rarely, almost never asked me anything, outside sex related things. I asked him about this, why he never asked me outside the sex question (which for me seemed like disinterest), I said he’ll want to know what my favorite thing is (favorite show?) if he really was not in for sex things only.
He didn’t answer then boomed! He blocked me next day. So, is this a confirmation about my ‘accusation’ or any ideas?
