OW was an acquaintance through FWH as she was a ho-worker of his.
There is no way in hell I would ever want to speak to her again.
I agree with what you said about the fact we forgive our spouses if we R but I don't see why I should go out of my way to R with It!
I have forgiven her for what she did but R with her in any way?
I would rather eat snot with a slatted fork whilst attached to a highwire via my nipples than ever have a 'relationship' with OW as the former would be less painful and far more palatable in every way!
