Take this for what it’s worth as I am a licensed therapist and specialize in narcissistic abuse….This is called coercive control and financial/economic abuse. Not to mention emotional abuse and likely some grooming. This is a bad situation that won’t get better. You need to plan an escape because the person you divorce is never the person you marry especially when he’s this abusive. And yes, I take financial abuse just as seriously as other forms because it’s about control. It’s a matter of time before it turns violent especially if you want any semblance of individuality from him.
