Suspicions she's lying?

If she is your best friend, you should discuss it with her.. if she tells you to fuck off etc, she obvs isnt worht being your best friend.

 

Leave her. Screw that man. If she cancels on you then say fuck you and move onto the other fishies out there.

No reason to waste another second of your life on someone like that.

 

If you guys aren't dating then I think you shouldn't think about it too much, since she's just a friend to you. If she was your girl friend then it would be a different scenario. And also, I would suggest not saying anything about this to her. If you accuse her of lying then I think this would hinder your friendship with her and she might not be the same to you. I say, let it go, don't make such a big issue about it. It might be that she wants some time alone with her boyfriend so let it be.
