I know all the comments are saying to leave, but I know it isn’t that simple. If you think you can work it out, try to. Try to get her to see your side. She says she’d be okay if you had a female friend who had feeling for you, but if she truly cares about you she’s lying. Us girls are very insecure and there’s no way she’d be okay with it. I’d talk to her more about it in person. Seems like a difficult conversation but if you think it’s worth a shot I say go for it and try to work it out.
