Ofcourse he can control! Would he say the same thing if his mother is after his colleague or his boss? No! He will be mad at her !! If my MIL (or anyone) treats me badly, I expect him to be mad at them. I’m not some slave! If I don’t have that position in his life, I’d rather be single. I’m saying this as someone who has been through a lot of harassment from a Narcissist mil. My husband was blind! I don’t wish that pain and suffocation on anyone. It was the worst time of my life. Thankfully he can see partly now and clearly understands I don’t put up with abuse and harassment. Kind people are always welcome. I tell him to treat me like a colleague first. As a wife, I deserve more love and respect than a colleague. If that’s too much to ask, colleague is my bottom line.
