My now ex and I separated a little over 3 years ago and divorced at the end of 2022. It was all deeply unpleasant and expensive for me as he didn't hire a lawyer. Since then, we have had very limited contact, and he has virtually no contact with our daughter.
As part of the divorce, I had the choice of buying him out or selling and splitting the proceeds. As we'd moved from North London to the West Coast, we only had a small Home Equity Loan. In the terms of the divorce, if I bought him out, I'd have to take on that loan, but if we sold it came out of the equity first before other disbursements (eg before his or my share, so we split that debt).
So, I sold the house in December and have bought a nice little place for me and my daughter, with a hefty mortgage.
Tomorrow is our daughter's birthday and today he emailed me to say he thought he wasn't supposed to pay half the Equity Loan, and he's talked to a lawyer about it.
I mean bad enough to be querying the settlement agreement 2 years later, but the day before our daughter's birthday??? Oh, and he's barely acknowledged Christmas or her birthday since we split. At Christmas he sent her what he thought was a funny card with Happy Birthday crossed out and Merry Christmas scrawled over it.
But I'd still be unreasonable to call him out for it on FB, wouldn't I? He blocked me for a while, then unblocked me in a fit of weird pleasantness. We're not friends on FB, but we still have plenty of mutuals, including a lot of my family members.
YABU - don't call him out publicly, it's childish
YANBU - call him out, the utter chiseling bastard!
