You're not overreacting. He is being controlling; his way of doing things is better in his mind, which naturally will make you feel like your ways of doing things are inadequate. Him saying you're overreacting or him saying it's your MI is a form of gaslighting and also exhibits his control. I would not appreciate this at all, if it were me. My husband used to do the same to me until I pointed out point blank what he was doing, and how it made me feel. Now, he hasn't exhibited that kind of behavior since I brought it to his attention. Maybe tell your husband to back the F off and let you handle things the way YOU like to do it.... if he's helping, then it can be a mutual decision of how it should be, but not a one-sided thing.
