My DSon in law who has been married to my DS for many years and had always been lovely has started to bitch about my other two DS. He will make comments about their parenting decisions. The way they spend their money, their lifestyles etc. he will always be nice to their faces
I don't know why or how to approach it. I certainly don't want to fall out over this. My lovely DS seems to ignore it and makes no comments. It really bothers me as I love all my sons and partners equally
