he asked " what is this"

After hooking up for 4 months he finally asked what is this 3 X in one day. And I didn't really know what to say. He said that he likes hanging out with me and he would want to try with me and I said and "what if it doesn't work out" and he said "well it doesn't work out" The only bad thing is he said this all while DRUNK. When he sobered up a bit he asked me again but I said do you remember what you said? And he said no.... I ended up saying I don't want to be a burden to you. I don't want anyone to feel forced to text me or go out with me and he said it's not forced it's mutual.... idk :| I like him and I think it would be nice to date him but I just got out of a 3 + years relationship 10 months ago. It's scary to think of starting something new.... and also it sucks that he said this while drunk ( mention that he would want to try) how much truth is in drunk words?
