Maintain your position. When your son is 20 and wants to know why the marriage failed you can tell him :
"I never stopped loving your mother. I NEVER MOVED ON during our marriage. Your mother divorced you and I to run off with OM which never worked out anyways... It was a tragic waste. But, my son, KNOW that I always maintained I wanted to save our marriage and that I wanted her to STOP CHEATING."
You DO want to be able to say something like that in 20 years yes?
Stop saying you've moved on then. Just hold your position and remain respectable...
Put your son first in every way, through divorce etc. Your wife's affair WILL NOT LAST LONG TERM... They never do. Especially when someone is vocal about it being harmful and destructive...
I am not saying run around town like a fool yelling at the top of your lungs, but if the subject comes up... maintain your position... Don't say you've "moved on"... that legitimizes her affair.
Detachment is what you are aiming for... its discussed at length on this forum... This is the direction you need to take.. not "moved on".
