This sounds like a question for a domestic relations attorney, and not an immigration attorney.
Are you also not a U.S. citizen? If not, are you worried about the impact of the deteriorating relationship on your own status, or lack of status? Or are you wondering about possible immigration benefits related to the abuse? What is the immigration aspect of your questions?
1. Call the police and report him,
2. call a domestic violence shelter or hotline and ask there advice,
3. when you are separate and safe file for divorce,
4. the courts won't take your son.

This is a domestic relations question, unless you are also not a citizen. Then there is the possibility of an immigraiton issue for you.
You are being subjected to abuse and what your husband is threatening is a crime called parental kidnapping. You need to get to a place that is safe for you and your child and start the process for obtaining a divorce.
If you don't have money to hire an attorney that's okay. You may be able to get some free or low cost legal assistance in your situation. This is a good place to start:
Even if they cannot help you you can always contact the local court and ask them about the *process* (they cannot tell you what the law is) for starting a divorce action pro se. Ask them if there are any self-help guides the state or court provides.
Not having money shouldn't stop you from doing what you need to do. Best of luck.
You need to call the police for you and your son's own protection when he threatens you or your son's safety....and also it creates a paper trail for when you do go to Domestic Relations court. Also, a DR court will not take your son away from you just based on not working. Also, you could call ICE and report that your spouse is an illegal alien...typically if you call the police for a valid reason and he is cited, they will typically report to ICE if they have an illegal alien in custody.
