Would you move on or fight it out in divorce court?

My friend husband is in the military. They have 4 kds together. He lives wit his mistress whom he has been living with for now 3 years and they have a bby together. He asked her for an absolute divorce she counterclaim that she wants him to be chrged with adultery, alimony, and marital property. My friend claims she left him but they were suppose to be working it out. He lives in VA and she is in NC. Since they separated she has been getting court ordered Child support from him. I told her to move on BC if he is chrged with adultery and get kicked out then she will lose her and her kids military benefits. Like medical,dental, commissary, and the amount of child support. What do you think?
