The explaining myself 100 different ways all the time stops right now. Time to put my energy into a plan to get well and get out.
YES.
This 100%
This is all you need to do.
You know you sound lovely and he sounds absolutely chilling, don't you? He sounds insane. Your therapist knows it too. She's not allowed to say that but her reaction to all this is clear. She must have been worried about you and she can see his manipulation and coercive control of you a mile off. He is abusing you mentally - and it's been very effective and that's why you're in the state you are.
If you can manage to drop this rope it will give you SO MUCH ENERGY. Right now he has you exactly where he wants you - running in circles trying to justify yourself and explain explain, so that he might see and change. But he does see. He just likes it this way and doesn't want to change. He wants to control you and pick at you and mentally batter you. He loves doing it!
So yes just stop. Come up with strategies to tune him out, whatever he says - yep ok dear. Whatever you say. What a nice man you are. Etc. Anything to shut up Hannibal Lecter.
Take strength from your daughter, your dog, lovely sunsets, anything (you clearly already do, you are far more grounded and able and mentally healthy than you think!)
And use that saved energy to make plans to get out. People here will help with that. Woman's Aid, too. Yes you qualify and yes you are being abused and controlled.
You can do anything you set your mind to after surviving a nutjob like this.
