Ok, bringing this thread back to Noles Fan, my vote would be to suck it up, live w/ it, try to forget it or whatever, but I don't recommend you telling your W about your one night stand or however long the affair lasted.
I think the only reason MY H told me was b/c of HIS guilt. I would prefer to have not known about him cheating on me.
But, as I said, this is just my "vote" or opinion that you NOT tell your W. Let it rest in the past.
