My DD has a friend she's known since primary. This girl has lived at our house for months while her mum was travelling and they're inseparable. Both got into university.
Friend's parents are divorced. Acrimoniously. Her dad was supposed to pay maintenance and child support but his previously highly profitable company suddenly/ mysteriously found itself making no money so he's paid nothing.
Mum working 2 jobs hence the travel.
DDs friend gets a maintenance grant but not a full one because of her dad's previous income. Her mum is barely holding on so DH and I discussed things and decided to take both girls university shopping for stuff today, and we'd pay. Friend was very grateful and happy.
We stopped for a coffee (in a retail park) and who should park in a space in front of us but friend's dad and his new girlfriend. Anyway he sees DH (initially not me, DD or friend) and moseys on over to say hi. This is where the AIBU comes in. DH shook his hand, got introduced to the girlfriend and then said loudly "Very sorry to hear about the business failing. Must have been such a shock. Any time you fancy a pint (on me!) let me know. Also, don't worry about (friends name). We love her and are happy to get all her university stuff for her". Girlfriend froze, he froze, it was funny and awful at the same time, then he saw DDs friend and scarpered.
This is the was husband unreasonable question. Friend loves her dad. She hadn't seen him for ages and was really hurt when she saw him vanishing. I think DH should have just zipped it and perhaps he'd have stayed and spoken to his daughter who ended up quite upset.
DH is bullish and said "the man's a c*#t and I'm happy I embarrassed him".
