I'd tell their wives and divorce her along with having her write down it was on her for cheating with these men. If she doesn't do that I'd steal her phone from her and use that as evidence. I'd also steal her diary on her too to use as evidence.

It would be pretty much impossible for me I feel to really want to or be able to trust them again if they did that. She just hopes she can get away with hot steaming sex to get away with it.

Though could go about counseling but really there is a line and I feel 3 men is crossing it. Personally I'd feel 1 man would be crossing that line. I wouldn't refer to her as being a good mother but I noticed you put it in quotes because yeah it really isn't true. A good mother wouldn't be sleeping around on her husbands back and putting their parent's relationship at jeopardy.
