AND - you have the capacity to be satisfied with a simpler life. My ex was like yours - never satisfied, always wanting more. We lived in a rich enclave and even though he made over $300k a year, he was always jealous of those who had more. He felt ENTITLED to more, rather than grateful for what we had.
Since my divorce I moved to a very middle class neighborhood. My house is actually nicer because I'm not paying a big premium to live at the beach. I manage my money well and stay out of debt. Sure, I'll have to work much longer than him, but I enjoy my work.- and I actually COULD retire earlier if I wanted to downsize considerably, I just choose to keep working for a bigger financial cushion and to help my kids. I'm creative and good at finding bargains so my house is nicely furnished at relatively little expense.
The key to all of it is living within your means. Check out the Mr Money Mustache blog for inspiration, plus I also love an old set of books from the Tightwad Gazette. Teaching your kids how to live well on a budget will set them up for success in life.
Don't let him push your emotional buttons when it comes to the divorce. He will have to pay you alimony, and half of any assets. You can develop a side hustle to up your earnings after the divorce is done. I can tell you are intelligent and resourceful. You can do this! And I'm betting a year from now you will be in a much better place.
