Well. As I see it, you kind of already rejected her so really it's what matters more to you, your friendship with the girl or the possibility of rejection and your other friends opinions. Everyone grumps about friends that they spend a long time with. Small things they do slowly become major irritators but that's because we're all different. I'm sure your other friends will understand.

I mean, personally if it were one of my favorite friends I would apologize and try because my friendships mean a lot to me and even if you get rejected it's not like that would change what it is currently. The possibility of rekindling a friendship vs 100% not friends. I would take the chance any day!

I would urge you to make the decision soon because it's obviously stressing you out.
