I wanted to add. If I were to find out he had an affair or was thinking of having an affair, I would still want to work our M out to a R. If it were with my sister....as crazy as that seems to me, I honestly do not see that happening...it would take a little more thought before I would want to stay together.
I admit there are some red flags in his story that could point to an EA or PA. At this time I am still not 100% sure he is, but there is a small amount of doubt that he isn't.
He gave me 'permission' (his words, not mine) to start dating. At the time I told him no thanks. If he mentions it again I may say something like: "Hey, maybe I will!" or "Hey, that's something to think about.."
