I'm sorry that you're having to deal with an abusive spouse. This is not healthy marriage you're currently in... in fact this isn't a marriage at all. Your husband is way too controlling.. to the point of it being abusive. He treats you like an infant child instead of his wife. Your husband does not have the right to remove your name from the joint account without proper consent according to the Consumer Financial Protection

I have a joint checking account with my spouse. I would like to remove my spouse from the account. Can I do that? | Consumer Financial Protection Bureau

I encourage you to take a trip to the bank to see what's going on... and how he manage to get your name off of the joint account without your consent. I don't know where you're from, but the penalties for forgery (If he somehow forged your name) is a Third Degree Felony punishable up to 5 years in prison.

He seems very unhappy in the marriage.. threatening you with divorce. The only advice that I can give to you is to go to marriage counseling.. if he refuses and has no ambition to save the marriage then give him what he wants.. a divorce.
