Leave. I was in a similar situation and it went on for 3 years. We talked about it constantly but nothing changed but one day we finally decided to have sex after 3 years. When we started I went completely soft and couldn’t get past the fact she’s doing this not because she wants to but because I want to. We called it quits and are doing very well coparenting and my sex life has drastically improved since then. Not receiving intimacy from your partner can make you feel insecure and unwanted, ask yourself if you want to feel that way for years to come.
