Yes, it’s a form of gaslighting, and emotional abuse.
Him grabbing at you for sex.
Him not listening to and belittling your concerns.
Him turning the conversations round on him so he’s the one getting the sympathy for the thing you’re upset about.
All shitty behaviour by him.
I do wonder if your health anxiety has actually been caused by his systemic crap treatment of you and I do wonder if it would disappear if he wasn’t in your life.
You aren’t overreacting at all. You’re stating your boundaries and he’s riding roughshod over them and the fact that you’ve tried to talk to him about these things and he’s just dismissed them and turned it round to make you feel guilty for HIS bad treatment of you is just appalling.
TBH, even if you did keep quiet about these couple of things in the future, he’d only find something else to get arsey about.
It’s him, not you and I doubt you’ll change him (because he won’t listen when you talk to him, which means he doesn’t want to change, not for you and not even for himself).
