Most Helpful Guy
Liking someone and being in a relationship are two different things. He likes you, the drunk thing just helped him get it out. You shouldn't judge the statement about not being in a relationship to seriously. That can mean crap ton of things. Going out a time or two to feel things out isn't a commitment, its just a date and it doesn't mean he is trying to take advantage of you.

It seems, pie eyed or straight, he is really Into you here, dear, and even off the job, he is Not afraid to announce it.
However, this doesn't constitute a Real relationship, which he Openly had admitted he is Not Into, so go slow with his flow and who Knows... You may end up hanging and painting the town red after hours.
Good luck. xx
