Upvoted, unfortunately it happened to me. I out-earned my spouse by 4x and lost everything when she decided she wasn't happy. Do not expect any gratitude : You have no idea who your ex-wife until you meet her in family court.

My ex wife took half of our (my) assets (including my 401k).

The lawyers took what was left as I was fighting to prevent her from moving away 3'000 miles with our kids (I had to pay for both her and my lawyer) In the end my ex wife won her move away. I lost my kids and I am now stuck paying more than half my salary in child support + child support add-ons such as private school, nannies, healthcare. The remaining of my salary is spent on travel across the country once a month to be able to see my kids.

It is a very risk bet... you don't have much to win and a lot to loose if you are a men (custody) and the higher earner.
