From what I've collected through my experiences, once you cross that invisible line between 'friend' and ... well, beyond that, it's VERY hard to come back over, either way. I've had a best friend for like 4 years, and early on, I shoulda made a move b/c it was SO obvious at the time that I had an opening (no pun intended), but I didn't, and now I'm stuck(not that it's a bad thing) as a good friend. I mean, sure, I could try and make a move, but I think both her and I are very weary of what might become of our long friendship if we waltz off into uncharted territory. So I'd say make a move while there are still moves to be made, because before long you're going to be categorized one way or the other. Good luck man I wish the best for you, and that you might actually escape the 'just friends' label. If you do by chance, please come back with tips, lol. ~
