I agree a little too. personal.
Question me, I don't care, long marriage, he had an affair, denied all the way.
After so long it really wouldn't have mattered whether we stayed together or not, he wanted to, still does but it would have been fruitless for him as he was no longer my friend, I would have never discussed anything personal with him again, wouldn't have had sex, and I wouldn't have taken him into account for one iota.
He would have been relegated to an inconvienient stranger getting in my way.
I don't offer excuses for inexcusable behaviour.
When women forgive men and apparantly stay with them it doesn't mean nothing changes, often the wife re writes the rules, their worst fear has been delievered, they have got throught it, they cannot be hurt in the same way.
The love is tarnished and many of the betrayed put themselves first even if they remain in the same space.
