So I've been married for 15 years and have 3 kids under age 11. I make $260k in a HCOL area of California.

I also have $130k in a bank account and $350k in my 401k. We own 2 properties, our primary and one of which we rent out.

Since marriage, my wife has never been able to keep a job. She worked at a couple retail jobs and hated it. She was a lower paid preschool teacher for a while but the stress got to her and she quit for a few years and hasn't worked the last 6 years.

She got her elementary teaching credential and after earning it decided she didn't want to work with kids anymore and now is just a SAHM. She knows nothing about finances and has no clue about saving money. Anytime I call her out about this it devolves into an argument and I'm the bad guy always.

I love my kids and would be happy to support them as much as need to financially for as long as I need to, but looking at misc alimony/spousal support calculators I can't fathom paying her ~$9k indefinitely based on the 50%/40% method.

Has anyone else ever been in a similar situation? What was the outcome? Am I basically screwed one way or another?
