You are still probably going to want a lawyer to help you terminate his parental rights, even if he says he will voluntarily sign away his parental rights. If nothing else, this man has abused you, and it could be dangerous for you to have contact with him. You also want the proper procedures followed with respect to the termination so he cannot come back later and say that somehow you did it wrong and the judge shouldn't have signed it.
But yes, for that time period without him supporting the children or being part of their lives, you can probably get his rights terminated.
