What Is A Guy Supposed To Do If A Girl Started Telling Him That Her Boyfriend Is Cheating On Her?

maybe she wants to cheat on him with you...elementary but that is how it is. i can't see why she would continuously bring it up. then again she could just be venting. if you dont have an interest in her sexually, just let vent until she comes out and says exactly what she means. if she doesnt then i would gather she is just venting!

well if i could put myself in the blokes position (this will be hard considering im so femme) i would support her as a friend at that time as she obviously needs me. I wouldnt make any rash decisions if i felt more for her than a friend ... purely because she would be vulnerable and maybe on the rebound. things are all about timing! x

You mean what is a girl supposed to? Well dont jump to conclusions. Learn the facts before you make a decission. Before you decide to take action see if her accusations are true. Dont assume she is correct. People often let their feelings take over, if the guy is cheating. Only you thing you can do is Bye-bye and go out looking for a new one.
