Divorcing fathers support group?

A good friend of mine is going through a separation (he and woman arent married but have 2 children together and lived together for a couple of years). She is being completely unreasonable, demanding, and just flat out mean. Hes been paying for half of the household altho she works in the med fields and hes in labor/construction/etc and makes more rhan him while helping his father pay for his stuff while having cancer treatment. But the house is in her name, they got into a fight and tge car the mother inlaw cooerced him to let her be his creditor (she pulled the you don't plan on leaving the family do you card) was going to get reported stolen after 2weeks late once so he went ahead and liquidated his debt w her thus leaving him in 0s, which lead to homelessness, which lead to hard time getting jobs bc no work truck nor stable place to find paperside of contracting, etc etc etc.

In short, shes fuckin him hard and using the kids as leverage. Is there a group or someone he could turn to for at least some guidance if not help? Hes an honest man. Bends like a pretzel for his family. The tyoe of man whos handshake means somethng. Through all this bs still refuses to even call her any names or anything. Any advice or direction is appreciated.
