Would you live most of the time away from your family to double your salary?

My son in law’s boss has given him a new large 2 bedroom , 2 bath totally furnished apartment with two pools and workout room in a large city two hours from home, wife and two great kids nine and eleven. He is that good at what he does. He tells my beautiful, slim and intelligent daughter she can spend as much as she likes and can book vacations with any hotel she wants. My daughter and her kids will drive to visit him about once per month. He has lived out of town for about a year to make double his salary. Do you think he’s avoiding her? They have no mortgage anymore and own two parcels of land. He doesn’t really have what I’d call a home anymore. That is, he comes back to the apartment at night and has gained a scary amount of weight since this began. I know he loves beer and that she has nagged him about it for years. He comes from an alcoholic family. Don’t men like coming home to their families that much anymore or am I being old-fashioned and stuffy? What do you think of this arrangement? She has been so irritable lately but they’re going to the Bahamas for two weeks soon with their kids.
