I can't say I'm completely understanding of your situation or that I have the perfect advice as to what to do, but I just felt like I should leave a comment. :x
Hmm. From a guy's perspective, and from what I get from what you said, I would also feel kind of.. rejected? Or maybe hurt or ignored if, like, all communication was cut off for such a long time. I don't know how he is as a person or how understanding he was of your situation, though.
As another odd note, maybe he's just a really friendly guy. And he has really friendly female friends. o_o
One thing I didn't get, though... are you two actually a couple or just.. you felt it was going in that direction?
