You need to tell your boyfriend that he’s bringing up his ex-girlfriend a lot, and you were wondering why. By broaching this subject you may be making him aware of his behavior for the first time. 😮 In other words, he may have no idea that he’s doing this at all. So by simply making him aware that he’s mentioning his ex a lot, you may solve the problem altogether.
If he continues to bring her up even after you talk to him about it, your first tactic is to not let it ruffle you. Humor goes a long way in this strategy. For instance, if he mentions what a great spinach dip his ex-girlfriend makes, you can smile and say, “You know, we should have your ex-girlfriend cater all our meals for us because she’s such an [i]amazing[/i] cook!” And then smile at him. He’ll get your ribbing him as a good natured reminder that you’re not interested in having his ex-girlfriend in so many of your conversations together.
It’s best to assume that he just doesn’t realize what he’s doing right now, and that he just needs some gentle reminders that he’s bugging you by bringing her up. Keep it light, but take care of your needs, too.
I hope that helps! 🙂
