@Faith50 AP forced my hand in telling DH. But our marriage was stale and long over, he was still incredibly hurt and this is something I have to live with. I will never cheat again, it was completely out of character and DH initially kept telling me it was fine, it must be the menopause, we can get over it etc until I told him again I didn't want to, I wanted to separate.
I still see AP. He tells me over and over how he feels, like he never has before, buys me sentimental gifts and I am sure his outpourings are genuine. He has a tricky situation at home (no children, other stuff going on though) and there has been excuse after excuse for staying.
His wife knows about me, but enjoys their lifestyle and completely controls every aspect of his life.
I have to admit, having waited for so long, especially through the lockdowns etc of the past year, I am getting bored now. And I should walk away. There are a dozen reasons why I should, but I have so far failed. I talk myself into it, rationally, reasoned arguments for leaving him to it and then I meet up with him again (we see one another outdoors daily and as I live alone he has spent some time at my home too) and I am sucked right back in. He is like a drug to me.
My husband has moved on, been with the same person for over a year now and is happy, and I am pleased for him.
