I took a female friend of mine to an event with a group of my male friends, a lot of them were impressed by how well she could participate, but a few of them just want to fuck her. One in particular, who is away for the next month, is messaging and chatting with her in order to 'prime her' for when he gets back. This includes shit talking me and his other friends in order to disqualify us in her eyes.

Obviously, her respect for me trumps this honestly disappointingly pathetic display so she half laughs at it and is half disappointed because she kinda wanted to screw him, but I digress.

The problem isn't the girl, I've got that under control, but I now have a friend whom I respect waving a massive 'I'll throw you under the bus for pussy' red flag. My plan of action has been to tell her not to rely to him as soon as he does that (which she follows) and if it gets worse to confront him about it. Is there anything I'm missing here?
