I'm not going to judge you.
Nobody knows the full story here.
I was never really sexually attracted to my first husband. But he was persistent (I had very low self esteem), and kind, and he was my best friend.
We had 2 kids and got married, all by 25.
Anyway, I left him for someone else at that stage. He had become obese and I just couldn't do it. I know it's cruel, but I found him completely unattractive, and the thought of no sex ever again, at 25.. I couldn't do it. Obviously, I should have just left, not started to chat to someone else first (I still feel awful about how I treated him) but that's how it happened.
He and I are really good friends now, 14 years later. The first year after the split was hard as he was understandably very hurt. But since then we've been very close friends and Co parented our kids very well.
The guy I left him for turned out to be a lying, porn addicted, drug addict who was violent (karma or what 🤦🏻♀️). Took 7 years to leave him. My ex husband actually helped me through it and insisted - on the times I cried to him that I deserved it - that absolutely nobody deserved that.
Anyway, that was 4 years ago. I've been with my new wonderful partner for almost 3 years, we've bought a house together, I have my teenage kids 4 days out of 7 every week, we have a toddler together, and I'm happier than I've ever been in my life 😊 Also, he's the most attractive man I've ever seen, so that helps😜
Sorry for the essay, I just wanted to share my story. I guess it's also a bit of a reality check for you that there are worse things in a relationship than not fancying him, but there are also much better things out there, if you want it. Good luck 💐
