I feel you. Something else that annoys me is girls talking about guys in general. I've never had a girl I'm dating go on and on about her ex but I have with general girls I'm conversating with. I say "Hey, not to be mean or anything, but I really don't want to hear about your ex." They usually smile and get the point. I'd suggest you do the same.
Peace.
So live that you can look any man in the eye and tell him to go to hell.
