TTC or quite?

What should I do? My story maybe sound similar to many of us here. Last night my fiancé and me went to Halloween party at soon to be mother in law house. Of course my fiancé has many drinks. Then we back home. Make long story short we are TTC and I am on my ovulation windows we start our baby dance. This was make me confuse and sad today. During our baby dance intimate moment. My fiancé somehow has to many drinks and start talking that he want his EX girlfriend to watch how we intimate and all kind of things but once that stuck me and turn me off completely when he said he would not .... inside her. Sorry for all stupid detail but I don’t know if I want to be in the relationship or TTC with him anymore because I feel like he not over with his EX stripper and his part toxic relationship. Anyone of us here ever have this happen to you? How do you handle it?
