Yes, it does sound pretty invalidating... even infantilising where your mom is treating you like a child or thinking she knows (best? better?) how to manage your own life.

You are entitled to make your own choices and yes, mistakes. I am sorry that she is not supportive and instead, undermines you.

I am glad you mentioned moving out as flying the coop and showing her your independence might curb (or not) this tendency of hers. But at least you would have some distance to live your life...
