Wife Having Emotional Affair With Work Colleague

[artsy]

^^^ it's not your place to tell OMs wife. It's his, or she needs to figure it out on her own, IMO. You two can't "force" therm to stop seeing each other. They have to end it on their own. I know that's not what you want to hear. Leave her be. Work on your own R.

If you tell his wife, you're doing it to punish him and your W. That's not your job.

Hang in there! Keep posting, there's some great advice on these boards.
