Wondering how women react to their friends engaging in affairs with married men.

Say, a friend of yours, comes to you and says she has been sleeping with someone who she knows is married with children - what do you do with the friendship? Does she remain your friend and you advise her against it, do you break off the friendship?

Curious to know how that goes between women when a situation like that comes up?

I had previous friends who slept with/kissed taken women but generally most guys just ignore it. We might say that it is bad behavior to be engaging it but ultimately they are their own person and we can't make decisions for them.

Has there been situations on nights out or at events where your friends have been openly flirting with married/taken men that you had to call them out on?

Wondering what the consensus is in 'the sisterhood' when these issues come up.
