"Yes these comments have been made in front of my husband. He knows it upsets me but stays quiet about the situation. He just says don’t worry about it."
He knows it upsets me but stays quiet about the situation.
HE KNOWS IT UPSETS ME BUT STAYS QUIET ABOUT THE SITUATION.
HE KNOWS IT UPSETS ME BUT STAYS QUIET ABOUT THE SITUATION.
just making sure you focus on the crux of the problem.
He doesn't want to upset his mummy, so he lets his mummy upset his wife. He doesn't want to feel bad by upsetting his mummy, so he lets his mummy make his wife feel bad.
He's basically delegating his upset to you. He doesn't want to feel upset, but he's just fine with passing the upset to you, for you to shoulder in his stead.
I would be reading the fucking Riot Act to him and telling him he either tells his mother to reel it in, or I would and she will not enjoy it one bit.
But - I accept that I am a bloody harridan these days, and you sound like a nice person who would struggle to behave like that, so we need to come up with another tactic. Although I still want you to keep in mind that he prefers that you be upset, rather than his mother or himself. Do not lose that truth.
Sit him down. Tell him that not only is his mother upsetting you, but his very obvious lack of support for you is upsetting you. HE is upsetting you, and what is he going to do about it? You need to emphasise that by him staying quiet, he is picking a side, and it's clearly her side. Make it clear you expect him to step up to the role of husband, and tell his mother to back off.
