Emotionaly abused,unhappy,tired of my relation with my husband, alone in this country no friends no family,I really need lo leave with my 2 kids,2 weeks ago I found a job but I can't yet support my kids financially. May I force my husband to pay to support my kids and how?? thank you.

Child support is a court ordered thing. Likely he will not give you anything until the courts force it on him. And depending on how mad he is at you or how much he does not want the kids, it may be a cold day before you see anything even with a court order.
