Emotional Affair Ended? Next step...

[mvgfwd2]

I think you need to think about your boundaries. I would hope a no contact with OM would be one of them. Like Missmeg says your W staying out with the OM when you left is a big red flag.

For me, I informed the OM's W of the situation. I felt it important to nip this in the bud from both sides and that I believed she shouldn't be the only one in the dark. It worked for me. Some on here would advise not doing this but it worked for me, but we weren't neighbors or friends.
