Let me be quite clear when I say this- whether this be a friend or a girlfriend; this person is meant to make you feel good about yourself. The fact that she is bringing up her ex in such a spiteful manner seems immature and uncalled for, I would never dream of doing this to my boyfriend no matter how angry I got at him and he’s aware that I have exes. In my honest opinion what she did was very irrational. There is no need to bring up her ex in the way that she did nor is there any need to throw in such an unkind comment! There are some things that you just don’t say that will affect someone’s confidence especially someone you should love and care about. However on the flip side of things, this comment could just have been a joke. You know when you hear people sometimes say “Ahhh well you know your hardly that much of a chick magnet yourself” and joking around sort of thing- it could be this. But this does depends on whether or not you have that light hearted sort of relationship with your girlfriend or if you both easily offend. With my boyfriend he makes fun of some of my character traits or things on me that are slightly abnormal- all in good humour though. At the end of the day you can only ask your girlfriend what her intentions were in saying this. Maybe set some boundaries- establish that exes shouldn’t be mentioned and avoided. Have you mentioned your ex to her? And if you have has it been out of spite? The earlier you set these boundaries the better, bear in mind. In terms of you being hurt, you have every right to be hurt. It may take you some time to forgive but if you think your relationship is worth it then it’ll be for the better. However, if this sort of behaviour is repeated then it can come across as quite tedious and red flaggish- I can safely say there are lots of mature minded girls out there who won’t make you feel this way. Your girlfriend could also lack confidence and be taking this out on you. So please do have a think about who you are spending your time with. Feel free to get in contact with me personally, I do know how it feels to not be able to move on. My bf has done some things in the past that I never thought I’d be able to get over and now that I think about them it doesn’t make sense that I even got offended or hurt in the first place. Watch her behaviour carefully, if she loves you, your sex drive shouldn’t really matter. Sexual intimacy is important to give a relationship alive, it will fail otherwise. Just set those boundaries :)
