This is is more of a rant than an aibu, but I am wondering whether I should've down more.
Backstory - was with ex for 8 years, split up last year but he sort of hangs round a fair bit. He has no friends or family and so far hasn't caused me any harm, is helpful sometimes and my children (they're not his bio children) get on with him so I don't see an issue.
I bumped into him at the supermarket yesterday afternoon just before collecting my DS and DD from school, and he was still chatting to me when the kids arrived.
My DD (she's 16) arrived and said she was thirsty so my ex offered a bottle of water from his van (sealed and brand new) so she said he's and thanks.
He gave her the water bottle, made a stupid joke about only drinking once from it but it was clearly sealed so she laughed that off, but then she helped down about half the bottle, went to take it from her mouth and my ex reached over and squeezed the bottle!
I felt awful but it happened so fast that I didn't have time to react.
My DD handled it well, a bit shocked but laughed it off.
I was fuming, but as he was laughing all I could do was say how stupid it was, but I think I should've been angrier and told him what a dickish thing he'd done.
He just kept saying over and over "it's just water" and "it's funny". At one point I said it wasn't, it was bully behaviour and he told me not to be stupid.
After my daughter had wiped her face I got her into the car, she half jokingly said she'd been cold so that hadn't helped but even that didn't make my ex feel bad and he didn't apologise.
Should I have done more? I feel awful. My daughter forgot about it once we were in the car and when it happened she did that 'shocked face with a bit of a laugh thing' but it baffles me he thought it was funny and I wonder whether he offered the water knowing he was going to do that or whether it was a spur of the moment things, not that it matters which it was...
