Well I have this friend and were talking... I like him.. a lot.. the other night I finally got the courage to tell him that we should go and maybe watch a movie.. he said he couldn't at that moment but he said maybe tomorrow... does that mean he's not interested? And was it a good idea to ask him out on a date?

I don't see any harm in it. Just don't rush things and let them naturally progress. Great relationships often start from strong friendships. You really have nothing to lose by at least asking him out to a movie, so long as you temper your expectations.

He didn't exactly say no... he said "maybe tomorrow". That makes it sound to me like he'll probably go when he's not busy.

Ask again - what can it hurt?
