Seeing alot of other people mentioning toxic friends who poison other women against their husband's. Is there any defence against this? My ex had a friend who she was spending alot of time with who was on her second marriage and the first one ended due to her claiming he was abusive.

So my guess is that she got in my wife's ear and turned her against our marriage. Looking back I encouraged her spending time with this women because I thought I was being a supportive husband and she needed some close female friends.

The sick part is this friend of hers was always nice to my face, so I had no clue what was really going on.

This scenario seems to be pretty common and I was just wondering if any of you had thoughts on ways to root these women out before they can do their damage.
