Most Helpful Guy
There is. It's called "Habit" and "Freedom". He's playing into his own demons believing that he is setting himself up for the same mistake that he made the first two times when he managed to achieve divorce. He's both nervous about a new resident & regretful about his own actions and the fact that he is "in the same shoes" that he was emotionally all those years ago.
Give him time. He will calm down with a little real-life reassurance that he isn't about to sign up to shoot himself in the foot yet again.
