OK. I got my strong feelings out and I apologize for my harshness in my previous post.

I will continue on now with a little more compassion.
As so many posters have stated, contact an abuse hotline. The national number has been listed.
If you do this, you will have a lot of support to move on. They can help you apply for government assistance if needed, and also for child support where it is set up that he pays the government program and not you. They will chase him down if he doesn't pay, garnishee his wages, take any tax return etc. All on your behalf.

They can help you deal with your fears, not only of him, but how you can financially make it on your own. One of the biggest reasons women stay in abusive relationships is financial and also deep seated insecurity/low self esteem. And those fears can be real. But there is help. Reach out.

I wish you the very best, and my desire for you is that you can find your inner strength to make any hard choices you may have to make.
