Gaslighting

My therapist told me my husband has been gaslighting me, probably for years. And I finally believe her. I don't really know what to do about it, but I just needed to put it out there, let it sink in I guess. My husband isn't stupid, I am. For years I thought he just had a spotty memory and was mildly incompetent, and I finally know I've been manipulated to agree and do almost whatever he says...
