Exactly the same with me. Married 23 year , 3 kids, youngest 16. you sitch is exactly like mine.

H fine up until recently. We even had sex with him initiating it 4 weeks ago. Now there is possibility of OW. I am in lots of pain. I to think it is the rejection. Lonliness.

I put up with exactly the same marriage as you are in now and it got me no where. I was in hindsight an available, doormat for cruel comments etc. The cruel comments is the hurt. You must validate them and I think say little.

He knows you are sorry, he knows if you could turn back time .....but we cant.

I dont know the answer for you. I just wished I had given up on m before the OW . Less painful and then I would of been in a better position to rekindle the marriage.

As each day goes by in mine , there is more and more ( often self inflicted) damage being done.

I write carefully as I really don't know you or your H or personality. I will follow you and see what other advice you get. No doubt I will also learn.

This is hard but by all accounts temporary.
