Thanks for your replies, everyone. The situation is a bit different than most of you presumed. We've known each other for about three and a half years now and we've already been romantically involved. Went through many, many things before ending here, both good and bad. And that's only the short version.
Anyway, things are settled now. Or should I say, things are being settled. I've confronted her with my feelings and the situation's pretty rough at the moment, but at least it's getting us somewhere. As
Ted Taylor once said, "Once you open Pandora's box you have to keep going, because Hope emerges last".
