I had done the same, mommy tracked my career for my kids and so my ex could be extremely successful in the same field. I do work in my field now but earning far less than me ex. He's also managed to stick me with most of the expenses related to our adult children that are not covered by the divorce decree (and there have been many - none of the three are quite self-supporting yet for various physical and mental health reasons).
Nonetheless, 11 years after our divorce, things are not all they seem in his life. Yes he's got the cool beach pad two blocks from his favorite surf break, and the cute Asian wife 19 years younger than him. But he's had 5 surgeries in the last few years (neck, lower back, and shoulders ) one of which was the night before he turned 60 (he never did well with birthdays ending in 0). Some of those surgeries may have been a result of ignoring a medical condition that I tried to get him to pay attention to 20 years ago but he wouldn't listen to me. Right now he's lying on the floor suffering from intractable pain due to nerve damage in his lower back. Despite his much larger income (twice mine at least even after alimony) and his wife's income he has not managed his finances well and is always crying poor. He's also wrecked his relationships with our kids. He's just retired but his medical condition is keeping him from doing what was planned, which was to take the early retirement and then work part time to keep his income the same, so now he has to live on the same income I've had for the last 11 years (plus his wife's income) and I'm sure he'll be whining about it.
Meanwhile I am in good health even though I'm 4 years older than him, my relationships with my kids are great. I've learned to play the drums and mallet percussion and have toured with my best friend who is a professional singer songwriter (and my ex thought HE was the musician in the family because he could strum a half dozen Neil Young songs that he learned in college on the guitar. Ha!). I don't live in the rich neighborhood he does but I live in a nice quiet middle class suburb and have room in my nice house for my kids. I don't have as much money as he has but I've managed it well so I don't stress about it. I'm not remarried but all the men I've dated since my divorce have appreciated me more than my ex did (and the sex has been even better than in my marriage, which was pretty darn good in that regard). I can't retire yet but I enjoy my work and am glad I am able to help my kids.
