I would make myself safe and then get back to school later, when I was safe. I just got my second degree and I'm 57; it is possible to go back to school but much much harder to recover from if he physically hurts you or the children.

I met a woman this summer from Pakistan who lived in London growing up and at one point her parents shipped she and her 5 sisters back to Pakistan and into arranged marriages; she was 16 at the time. Her husband was abusive (as were her parents) and her husband used her skills in English to teach/make money for him. Eventually they moved back to England for his job and from there she finally convinced him to emigrate to America. Once there they became citizens after a bit and she immediately got herself and children to a shelter and filed for divorce. She had planned the whole elaborate thing as she couldn't get a divorce in any other way and get away from him! She is now in her last semester at college, her children are older teens and she's finally getting a life.

Do whatever it takes to get away; then everything "else" can follow. There will always be excuses to not leave; and if he takes any money you get from a job, then what will you do. That will complicate things rather than help. It is "simpliest" now with good things in front of you. Go to a counseling center at school or the library, wherever to find what resources are available and get someone's help in planning how to use them. Write to a shelter in the next city or whatever and get their help. Go to the nearest university legal aid office and see how/if they can help you, etc. Make yourself a network of support and then do it.
