Dont sign

Dont sign, you will give him more ways to throw you into jail. He is treating you like a dog-you have to do what he tells you to do, well I have news for you, you dont have to. This documnet is a proof that he is abusing you, get him to sign it then keep a copy. You can sue him for rape, for abusing, for threatning, many other things (find a lawyer), he will be spending a lot of money defendin himself if you sue that he will have no time and money for other things. About that cancer
situation, he obviously knows it a long time ago, this makes him part of the insurance fraud, just tell him you can call the insurance company and tell them to go after him
