Don't listen to any of them. Be a stand up guy to your boy AND STAY AWAY FROM HER. That's a pretty shitty thing to do to a freind. Think about how you would feel. I'm sure if it was you that hit that and not some other guy it would make your freind feel even worse about it....(cuz he knows you) But if the IM was from her......tell your boy and see what he has to say about it. Maybe he will just say fuck that itch and tell you to hit it anyway Good luck.
