The best way, as you said, is to separate and retain a lawyer for the best out of the worst. When you have a good lawyer, you can have child support from the hu*****and; who's faust is normally not a consideration in deciding the child support.
The next-to-best way is to talk to the hu*****and, and have him clearly understand the consequence if he takes violance at home. This is the best way for a prevention to domestic violance. When it occurred, Americans might well possibly call policy. This happens to a couple at the university I went to. Police involvement puts the hu*****and one more step for deportation, but not necessarily. The person I knew was not deported, but he made a deal with police and never again beat his wife as I know.
Every case can be different. The best way is not getting into it: for both take care of each other and communicate rather than looking for the extramarital affair as an escape.
