Don't know what to do after drunken incident?

Well, what do you want to do? You barely know this guy, never having spent time with him sober. It's possible he has expectations of you based on your drunken behaviour. If you decide you want to see him again, I'd make it very clear that you were drunk before, and dont intend to get drunk on future occasions with him. Remember that you really dont know him at all, and take things very slowly, so that you can get a clear, sober picture of how he is, and he can do the same.
