Eavesdropping friend?

That is really nice of you to want to retain a friendship with her. However, she sounds like an immature b****. I really don't think it's worth it. She has been disrespectful to your girlfriend and you were just trying to talk about it to your friend. She shouldn't have eavesdropped and she shouldn't have been rude to your girlfriend in the first place. SHE is in the wrong. If she wants to approach both of you and apologize sincerely, fine. She sounds rather spoiled as if she thinks the entire world revolves around her. Why give her the satisfaction? Sounds like a friendship not worth salvaging. Sorry.
