My girlfriend wants to stay friends with a guy she slept with during the three weeks we were broken up. Since we've gotten back together, all this other guy has done is try to break us up. I don't want her to have anything to do with him. Am I wrong??

No, you're not wrong. What's her problem? Does she really want to be with you, or does she secretly want to be with him?

If it's obvious to you that he's trying to break the two of you up, it's probably obvious to her. She may simply like the attention, then again, she may be scheming to leave you and get with him. Be careful, be aware and do NOT be a fool.
