It's possible that it's a mistake and she didn't even notice (there's a reason I handled all of our finances...), or that she did notice and got so embarrassed and mortified that she can't even reach out to me. That still doesn't explain why she has my payment information saved in her PayPal, a year and a half after I divorced her, or why this has never happened before...

Thank you--the ochazuke was delicious. I'm tempted to start making a bit of extra rice some days, just so I have leftovers to use to make it.
