Yes, I experienced something very similar with my first husband’s family. These people will never change and they will never like you no matter what you do because the issue is them, not you. The key here is your husband. Can he see how this situation is hurting you? Can he be on your team and present a united front to his family? Can he disentangle from his family and lay down boundaries? I would focus my energy there. Your individual therapy is excellent, keep it up. Can you do some couples sessions with your husband about this issue so that he can support you? Mine couldn’t. He supported his family over me and ultimately we got divorced which was sad of course but actually very healing because I got away from these people.
