I need advice

So I on Social security and my husband thinks we can use it for his lawyer and I keep telling him if the lawyer is not for me then we can not. He keepsxspending my Social security money on drugs and keeps telling me he will pay me back but he has not. Like today I told him I think it is not a good idea to this but every time I tell him that he tells me "I knew you did not love me. I guess I will just have to go to jail and you will never see me again" I feel like I am not even worth it to him. I am always stressed about my Social security money because at the end of the year if i can not tell them and show them where my money has gone i can lose it. If I just being up money and just try the explain this he tells and screams. Tells me no one will ever love you because of you mental illness and what your mother and father did you. You deserve it. He says thinks to me that I worry about because of my childhood. I do not sleep at night because of my money situation. I just do not know what to do.
