It’s likely “ your money” because you both either work and are contributing fairly equally or one is home with kids by mutual agreement. I have real problems with one spouse making substantially less unless there are kids, and feeling like they’re entitled to take money from the spouse who makes more without asking.

My brothers wife refused to work despite having a degree and no kids. She was a hoarder and slob, their house had mice and roaches. He stayed with her 14 years before divorcing and she got 7 years of significant spousal support. It was the most unfair thing I’d ever seen.
