Should I tell my best friend that I love him?

So I met my best friend 3 years ago in out theatre class, I saw him and immanently thought he was really attractive. We talked and went on a date and after like a month of knowing him he asked my to be his girlfriend. Right after he asked me he just started to ignore me and we broke up; but stayed friends. We both had new relationships after this and we just became really close friends (best friends). Last year I started to feel like I like him more than friends. I couldn't get him out of my head, every love song reminded me of him, no other guy compared.. blah blah you know when you start liking some one how it goes. Anyway, I didn't want to tell him because I didn't want him to leave/ignore me. I tried everything I could to just stop liking him and get on with my life but the more I tried the stronger my feelings grew. Now a year later I am 100% positive I am in love with him. I have said no to dates with really attractive/ great guys just because I love my best friend so much.

Sadly, a few months ago he moved to New York...but the night before he moved he kissed me. I had no idea he would even want to do that before then! I feel like he might feel the same way but apart of me just feels like he did it for no reason. Should I tell him my feelings or is it too late??
