So basically as it always happens one drink to many and waking up the next morning to someone you only recently met. Well we have met up a few times since sober and not just sex. He says things like I can't wait to see you etc and invites me to places that are not sexually linked at all e.g. a friends birthday. So I'm not sure if it is the old fwb or whether he likes me, he has said that I am beautiful etc but is that said in the moment or to get more of whati already gave him. I'm not to sure what to make of it!

Stop having sex, and find out. If that's all he wants, he won't hang around for long.
