What would you do if you found out the woman your OH cheated with, a year ago now, was fishing around for details and trying to pass messages to your OH through a mutual friend? My OH has no desire at all to have any direct contact with her. But the mutual friend has no clue what happened last year so keeps talking to him about how she's doing (terribly as it happens, yay for karma!) and I want her to know that I know what she's up to and me and my OH are a team working together NOT to let her infiltrate our life again. But at the same time we don't want our mutual friend to know any of the gruesome details of what happened. We just want her to stop fishing iyswim? Am I out of order for sending her a polite and concise email saying what I've said above? And copying it to her husband too? My OH has worked very hard to undo the damage he did and he wants her to back off and stop using an innocent mutual friend as a go between. He agrees an email from BOTH of us to her, showing a united front, is the way to go. I just want her up crawl back under her rock. Her life and marriage is shit but that's not our problem and my OH will not be her fantasy escape route again.
