Yeah, marriage sucks anyway, I use to think otherwise but reality is cruel plain and simple. I married the best many years ago and she gave me a beautiful daughter, 6 years after her birth wife and daughter died. married second time years later and I know the feeling you describe but I stayed and it destroyed me. Widower and divorsted. Reality is cruel.

He cheats you leave, Good for you. Stay and stagnate or leave and live.

Better to be alone and happy, than with someone and miserable. How I wished I had heeded my own words.

Thanks for your comment. I am really sorry for your loss. I can't imagine going through that.
