Almost 20 years in. No assets prior to marriage. She is healthy, college educated 47F who has refused to go back to work (kids 14m,16f driving, same school) and always spent much more on herself and household things than I ever would have.

I have no problem with supporting my kids. But alimony calculators online show amounts that would make me live out of my car and take my kids out of their one-of-a-kind private school.

Other than emotional abandonment and almost daily marijuana use for 10+ years, I don’t have anything to hold against her.

Is there any hope, the kids and I don’t get royally screwed if I get divorced??

Get a shark lawyer and just cut her a huge check (from retirement savings)?
