DIL is the wife of YSS, sorry. The children are 5.5, it is the situation that has resulted in that comment that upsets me. Anyway, I think it may be a turning point for the better in the long run with your relationship with SS. Our EFH did the same think to YSS about 4 years ago, I would love to have been a fly on the wall for that argument! Anyway, she has refused to have anything to do with him since and guess what, he is a much nicer person for it. He is much closer to his dad and I now, and has begun to recognise who has been there for him all along. For these women, they are only interested in their children as long as they can control them. When the children grow up and challenge this, these women have no difficulty simply walking away. They show their true colours. Thankfully, SS has you two. Things should improve gradually.
