It's a shame, but he only has himself to blame. He even said it in an interview about how he's missed birthdays, thanksgivings, chrismasses, all the other special family monents for 23 years....and how enough is enough at some stage and he will have to put his family first etc etc. He retires and then because of this weoird obsession he has, and likely knowing full well it will put his marriage at risk, he un-retires.
She did her job, moved to Boston for him and I know people raise their eyebrows at multi millionaire Giselle raising kids and all the help she likely had, she still did it. Put her lucrative career on hold allowing him to be basically absent for 6 months every year. She even put up with a certified lunatic like Antonio Brown living with them.
I have zero sympathy for him. He must have known this was a distinct possibilty. Yet he still did it.
