About 6 months ago, I had a huge blowup with an adult married daughter. We’re slowly rebuilding bridges. Occasionally I still get frustrated with her and I will vent to my husband (her father) about certain situations. A couple times he has phoned daughter to tell her what I said when letting off steam. I have told him this is a betrayal. His excuse is that he’s trying to “help”. To me his actions seem very junior high mean girl, like he doesn’t want my daughter and I to be friends. She is his favorite child and I think he’s sabotaging me so he can be her favorite parent. Of course it could be that he’s just an old science guy with zero emotional intelligence and he doesn’t understand the nature of women’s relationships. Going forward I will journal my venting. Not sure if I can forgive him after the second time.
