>>2 I couldn't agree more!
Something similar happened to me a while back but it was the other way around: my friend still loved me and, as time went on, when I got in a relationship he literally went nuts, 'cause he thought I would have fallen for him again, eventually.
My point is, don't get your hopes up and give her the space she needs, she's free to do whatevs and so should you. Waiting for someone to fall in love with us without actually doing anything to make things go towards that direction is pointless. You should focus on yourself and what you actually NEED, since maybe what you guys are meant to be is being just best friends. Not that there's anything wrong with that!
I wish you both the best, good luck!
