I mean honestly his behavior sounds borderline creepy at this point, but I don't know him and I know you say you like him okay, so obviously it's your call on how you feel about it. But I'll just say waiting around that long and going out of one's way to talk to a person is kind of uncomfortable at the very least. It seems this is escalating and I Hope you are able to deal with it in a way that leaves you feeling like you maintained good boundaries soon.
