Husband told me he's going to stop taking CPS cases

My husband is a lawyer and he's one of the very few lawyers in our city that take CPS cases and he is allowed to be called in to be appointed to a case with CPS. He used to be a labor attorney and he told me today he's going back to that and private practice only. He's done with CPS cases. I've been trying to change his mind because there are very few lawyers in our area that do CPS cases because the pay is low and working with CPS is hard. My husband had a situation where he had a case and the woman went and lied on him saying he wasn't going to take her case when though he was appointed to her. He said he is taking her case. He was just being honest to her that he probably won't win it and she was blowing up his phone cussing him out. He said he's burnt out with parents who abuse and neglect their children. Don't do anything to try to get them back then when the state pushing to terminate their rights they want to act like it's his fault that he may not win the case. He's mainly tired of being treated poorly parents and getting paid shit for it. I really want him to reconsider. Again not many lawyers take CPS cases. I lost my son to CPS when I was 18 and they almost terminated my rights but I got it extended and did end up getting him back. He's doing a lot for families. He told me he misses being a labor attorney anyway and he's just going to do that but I really think he would be making a mistake.
