Thank you for posting this OP, I know this sounds like a weird reply, let me explain.
I am just out of a near 35 year marriage, a marriage that was one of companionship and three beautiful children but sexual difficulties from the start, which my partner hid well, and I adored him so believe the excuses given. Three pregnancies were almost miraculous TBH.
With hindsight I think he used me to provide his babies, once we had them he showed no interest in sex, in fact I would say that he was on the point of being repulsed by the idea.
I hadn’t had sex for nearly a decade when I called time on the marriage. My self esteem shot to pieces, not just no sex but that had now grown to no physical affection, in fact he just couldn’t bring himself to touch me at all, even holding hands was forced.
The reason I want to thank you is because this has been the most difficult 2 years of my life, so much so that just today I was wondering what the hell I have done. I am just a few years away from retirement and I will be borderline penniless. Your post has reminded me why I ended the relationship, why I am going through a difficult divorce, why I can’t wait to just be on my own.
So no, please don’t marry this man he doesn’t deserve you, and you deserve so much more. Getting out of a marriage is so hard, much harder than walking away from the relationship that you have. What your families think is neither here nor there. Your family should be supportive of you, whatever the reason.
If I was your Mum I would never want you to stay in the sort of relationship that I have had.
