DH and I have a mutual friend we have know for a long time. I'll call him Bob. We see him and his wife/family quite a bit. Last night Bob met DH for a drink and told him he's having an affair with someone at work. It's been going on for well over a year. She's not married and us younger. Bob and his wife struggled to conceive and went through quite a bit of IVF before their second was born (who is now 5 months) and he says the stress of this is what drove him to start seeing this other woman. As far as I know, Bob has no plans to end it with the OW or to tell his wife because he doesn't want to loose his kids, apparently.
DH is absolutely livid. They had a huge row and DH has told Bob he has until Sunday to tell his wife, or he will do it. He means it. Is this the right thing to do? On one hand I don't think it's any of our business but on the other hand I think I'd want to know if it was me in her position, but it's not about me is it?
I've tried to calm DH down so we can gather our thoughts a bit but he's determined to deliver his ultimatum. Anyone been in this position? What did you do?
