Gently, love, you have really bad anxiety that’s stopping you from working (not that working or not is the point), because you’re in a horribly abusive relationship. You’re treading on eggshells.
He’s supporting you financially, because he’s made you so anxious you can no longer go to work. Then he makes that support precarious or conditional, exacerbating your anxiety. He’s isolating you from your children and making that relationship as difficult as possible so nobody can intervene.
Your fight, flight, fawn response must be in overdrive all the time. I’m so sorry this is happening to you.
Before you met him, you had a house in your name. Presumably a job. You had two kids you (again presumably) had lovely relationships with. And he’s taken each one of those away from you with his abuse.
I absolutely believe you can also get all of these back- and it starts by getting rid of him.
Womens aid and the police can help you. The abuse is physical, financial, emotional and psychological. You can probably chuck coercive control in there too. It’s all a crime. Maybe start with carefully and secretly contacting Women’s aid for advice- they can help you navigate this safely.
And tell your family what’s been happening.
You can do it, love. It starts by asking for help though.
