This is a very dangerous situation. This guy will only continue to escalate. I am afraid for you and your family if you do not get him out of there. And where the hell is your husband in all of this? Shouldn’t he be protecting you from this abuse? Get this abusive free-loader out of your home and do not hesitate to get a restraining order if his threats of violence continue. This man is a classic abuser and he eventually will make good on these threats. Please take care of yourself.
