Unrequited love, I get - I've been on both sides (and indeed, am still friends in multiple situations). It sucks!
As a romantic, I totally understand the concept of that anguish...but, y'know, if you can't handle only being friends, you don't have to put yourself through it! Fictitious "zone" yet again evaded!
