I agree. Obviously, money is not an issue for him. He doesn't have to go to work every day to eat and pay rent, so he needs to take his millions and just go away for awhile. Do something else. Do whatever wealthy people do when they're not spending time worrying about paying bills.
If he decides that he does want to come back to producing at the level that he had been, he can do some intensive therapy and anger management and, after a few years, he can make his grand return and talk about the changed person that he's (hopefully) become. But the man is in his 60's, right? He's at an age when many people who have the means to do so are looking at retirement and beginning a new phase of life. So I don't know why he'd bother, really. He and his husband can take their fortune and ride off into the sunset and not deal with any of this.
