Help! My crush is moving away SOON & I've crazily decided to go for it. What should I do?

I'm sure this must be 'The last chance syndrome' because in other circumstances I don't think I will be feeling this way, it doesn't make sense (that’s why it is crazy) but whatever it is, I feel this way and can't do anything about it.

I went to high school & college with him, he is an ex-boyfriend from 5 years ago but we have remained close friends and we've always been in the same circle of friends. Nothing has happened in those 5 years between us except innocent & not real flirting, but everybody always nags us even though each has gone their own way regarding relationships...

Since our story has been so long, weird and, in times, turbulent and full of drama (long story, don't wanna annoy you with it), I didn't know if it was a good idea to say or do anything but I feel that if I don't I will regret and have a huge WHAT IF in my head, this is it...

So after thinking about it A LOT I've decided to go for it, despite some people think I shouldn't, the worst that could happen is to be rejected & to get him mad at me, but I don't think the friendship will be lost. Eventually it will get to its "normal" state again, as it always does... :)

Now, I need your help & opinion! What should I do? Tell him something, do something, being direct, being discrete? Any ideas?
