Partner often refers to exes in conversation and it bothers me.?

I m in a relationship where my partner very often refers to exes and old relationships. I feel like it brings in other women into our conversation and it makes me feel like I am always being compared to some "other" for example, when he thought I didn t do enough for him, he referred to an ex who took him on a trip. When he felt I didn t give him enough attention or not take off from work to a woman who was willing to risk her job to be with him. The latest was me using coupons, his first reference was..oh I dated this woman a long time ago and she was smart, industrious, and used coupons all the time.

I have asked him to please stop as this makes me feel he is comparing me to others instead of seeing me as an individual woman he is with now. He feels if he can t openly say whatever comes to his mind, he is walking on eggshells shells and I am too sensitive. He said, "I mean I could lie and say some guy I knew used coupons, but that wouldn t be honest and you re making me feel like I m censoring myself bc you are too sensitive"

How do I handle this? Am I being too sensitive or is it fair to ask him to please not refer back to some other woman unless we are BOTH talking about old relationships when trying to address situations that pop up.

Please help. This is making me miserable and I do not know how to communicate this to him, and or, do not know if I am being too sensitive....
