回複：Cool down. If you do not want divorce, the only solution

I don't agree with you on the last part "Then he will pay required child support. But he still has some chance to get child custody and ask you to pay child support if that is what he ask. ".

She should definiltely bring him to court for a divorce. The law in USA generally protects women and children. He will not only have to pay for the child support, but also the alimony to support her as long as she is not married or getting a job. He is divorcing her for another women, there is no way that he is getting the children's custody.
