I’m 40, my partner is 52, and we have two kids under five. We last had sex two years ago, but a few nights ago, we were in bed, and I woke to find him having a sex chat on his computer. He has done phone sex before. When I found out, we went to sex therapy. I want to leave, but I don’t want to not see my kids as a result of separation. I feel very angry with him. I don’t want to sacrifice myself for a man who can’t be bothered with wanting me sexually. I fantasise about other men and feel frustrated and stuck. It’s not fair, but I can’t leave.
