I'm sorry for this I have lived through it first hand. What I have to say to you is somewhat odd perhaps. He is preoccupied with his new woman, this is the time to strike with the divorce proceedings, put it in overdrive while he is distracted and has a good feeling flowing. He will pay less attention to the factors in divorce and the system while he is in this euphoric state. This is the time to get things in writing and set yourself up for the life that follows. Pay no attention to what he is doing other than to see this as an opportunity to strike NOW. While I know this sounds cold I know for sure this is great advise.
