He is a man who never admits to being wrong. when I raise any concerns he totally dismisses what I have to say- I tend to raise my voice due to sheer frustration he tells me i am shouting ( when I am not) and then he tells me i am abusive and a nasty person. then he will ignore me for afew days.
I can see how years and years of dealing with a drip, drip, drip of stuff like this could have led to this latest incident. He wouldn't be the first coercive controller to drive his victim to the brink so he could say "look, it's her, I'm the victim here".
Four years ago you tried to leave but he accused you of kidnapping your children and threatened to call the police. Are you afraid of what he'd do if you tried again? Are you afraid of being alone if/when your health condition progresses?
Op, I don't know what you hoped for here, if you just wanted somewhere to vent or if you wanted someone to give you a magic fix or something else...
Asking for help doesn't mean you have to leave, it just means you're asking for help. People can then give you info, and you can decide what to do with it.
I can't tell from your posts if this is definitely coercive control, but it's indicative of it. If you want to talk to people who won't judge you or make demands on you, but may be able to help you start making sense of the bigger picture and figuring out what you want to do about it, then you can always speak to Women's Aid or phone or email or attend the Freedom Programme. 0808 2000 247 for WA, or www.freedomprogramme.co.uk for their contact details.
