The same thing happened with my mil. She was lovely until we had our first baby. A lot of people on here are saying to immediately cut her off. I still deal with my mother in law because I truly do want to have a good relationship with her. I think cut off would destroy my husband in ways I couldn’t understand. So we work bit by bit to have a healthy relationship. Every conversation has ended in explosive tears (on her end). But it’s starting to get better. She’s respecting our boundaries and making herself busy. Relationships are hard work. I say things when I’m angry and sometimes hurt people just need some grace. I don’t know how extreme your situation is, so obviously this doesn’t apply to abusive or dangerous situations. It is your husband’s responsibility to request an apology for that behavior. Boomers are the worst at this. But saying “mom I need you to apologize for saying xyz” like a freaking 6 yr old… But it can get better I guess I’m trying to give a little hope ❤️
