Started dating this guy 6 months ago. Initially I wasn't certain if it was just a casual thing as we hadn't clarified our intentions. I was very upset when he joked about a threesome making me question if our relationship was solely about sex. However a few weeks later we had a serious conversation where we both expressed our feelings and agreed it was more than just physical. I mentioned how the threesome comment had deeply upset me, and he apologised sincerely promising not to make such jokes again. He reassured me of his commitment expressing distress at having upset me. Fast forward three months and he's made another inappropriate threesome joke today. He was very apologic when I got upset and said that he had forgetten our conversation. I'm thinking about ending things over this. Would I be overreacting?
I know the jokes are not in a malicious way and he would be heartbroken if I ended things
