<human>: I have been with this guy for a few months. I was anxious, afraid to show feelings, etc. and I broke up because I couldn't take the obviously strained relationship anymore.

He was always the one to show feelings, he's a person that gets attached quickly, etc.

So a few months after the break up - a few days ago, actually, we were both at a party on the beach and we were both drunk so we got in a fight that we both barely remembered, but we went out to talk it out so we wouldn't stay in bad relations.

We ended up talking about our whole relationship and everything - it ended with him kissing me and us agreeing to stay fwb or something like that.
He expressed his concern with his quick development of feelings, with the way it ended the last time, his worry I might find someone else, etc.

However, after a few days he broke it off saying that he doesn't really feel anything towards me, that he's just going to hurt me and so on.

I can't really ask him about this again randomly, before I could I'd have to try to get in contact again slowly or something, and I just don't know what to do.

I mean it happened so quickly and his behavior and his words in those few days were all kind of contradicted. 

Any opinions?

Could you distill the essence of the text into 1-3 sentences?
<bot>: Ex and I start seeing each other again, after expressing worry of himself getting hurt again he breaks it off with the explanation that he doesn't care and might hurt me. What should I do now?
