Sounds like a one in a million wife. Mine left me when I told her that my mother had taken my virginity and that before I started dating regularly, she and I had fulfilled each other’s occasional need during dry spells. And I was never prone to mommy issues. None of that was a thing either with my mother or my wife, no role play stuff, with either my mother or my now ex wife it was simply as a man and woman. But after the divorce, my mother and I had a long talk and said the hell with it, and decided to share a bed and live as a couple anyway. We don’t have family close, outwardly it is just a living arrangement presented as helping her and cost savings for me after a costly divorce. Sometimes we may go days or even a few weeks just sharing a bed, other times we may enjoy each other heavily for days at a time. But the best part is that we are a natural comfortable fit for each other in daily life, and neither of us turns the other down. Granted there are two things we decided were out of bounds. No side piecing each other if we do have a relationship (not that either of us actively looking), and no conversations about me moving on when she assumedly passes long before I do. Otherwise, we are both pretty happy about the trust, and ironically I am the one who regularly asks that we have a real date night. She never touches mommy role in bed, and neither do I. It just works.
