Hello and welcome, Izzard
Your post and verbage really got to me, could really feel the pain in your words. Working your dates backward, you were about 52 when you had your surgery. Which meant you either had kids much later in life, or you were on a second marriage at least. The fact that you have your daughters living with you still, speaks well of you on your opinion.
From your description, you and your wife were able to continue to have sex and lovemaking to some degree of satisfaction, despite having ED from PC. It is not like you had total ED, and you refused to try other solutions, i.e. injections. If that were the case, and you stubbornly refused to assist you wife in her sexual needs, only then would I believe that she left you for the potency of other man.
We don't know any of your other relationship issues from one post, and we are only hearing one side, but regardless, taking you at your word, if you wife was willing to walk away from you and your children, for another man, then what is that saying about her?
I have been married to the same woman for 35 plus years, I couldn't even imagine to understand the devestation and pain I would feel if she left me, especially for another man. So I won't pretend I can feel everything you are feeling.
You must be strong for your daughters, sounds like you are and you are willing to continue that. I agree with a fellow poster above. Keep your self in shape: mentally, phyicially, and emotionally. Continue your therapy. If you are a man of faith, re-engage in your faith.
You will be a good candidate for another woman, if you are back in your game, PC doesnt have to destroy that part of you. And there will be women that will work with you and understand your issues with your post-PC issue. Not to be mean, but you aren't a 25 stud muffin anymore, you are a man in his late 50s, things and desire and all change with the aging process.
What you want one day, is for a woman to fall in love with the man you really are, one that is attracted to the whole you, heart include.
You penis, whether it is cooperative or not, is not the entirity of who you are as a person or a man. You have to believe that in your heart.
