But, presuming there’s not also an issue of physical abuse or restraint on the part of the husband, the OP has a lot of control over this situation that she’s simply choosing not to use. She doesn’t have to wear a dress she doesn’t like. Even if she picked one to shut the woman up so she could finally go home, she could call back that night and cancel it. Presumably, she has her own car keys. She is free to leave toxic situations. She is free to change the locks on her home. If her husband insists on letting his mother change her home while she is not there, she can change it back. She can make it clear that it will always be changed back because this woman has no right to decorate her home without her permission. She is free to inform the hospital where she delivers that under no circumstances is her MIL allowed to visit her. She can tell the to have security on standby. (They deal with this frequently.) She is even free to file a restraining order, if necessary. She is perfectly free and within her right to protect herself. If her husband is not an idiot, he will not put her in the position to do these things. He will support having appropriate boundaries with his mother. Or he will see the priest or therapist and figure out why he has such a creepy relationship with his mother in the first place. But even if he is an idiot and won’t do what is right for his marriage and family, there is a lot that she can do to protect herself from being abused. But step one is the OP deciding not to be afraid of her husband accusing her of “hating his mother”. Embrace it. His mother is a nasty, abusive person and her distaste for her is completely justified. If and when her behavior changes, she will forgive her and offer another chance. Until then, she will protect herself and her child from the toxicity. If this man-child wants to pitch a fit and go stay with his mother. That’s fine too. If he’s calling himself a Catholic though, he’d better get his behind over to a priest and discuss the concept of “leave and cleave”.
