Family holiday with my partner and our kids for the first time (live in the US so can travel to another state for trips).
He has 3 kids, I have 2. We have separate hotel rooms on the same hotel complex.
Completely unexpectedly we got 3 hours without the any of kids yesterday after the stars aligned.
Told him to text me as soon as he got his kids settled at their activity.
Obviously quite excited for some alone time.
Almost three hours later I'd heard nothing from him. Then 10 mins before the kids were all returning, he text to ask where I fancied meeting with the kids for dinner later.
When I asked what he'd been up to he said he'd had a lovely 3 hours. Hot tub, went for a nice walk, read his book.
We went on to have a perfectly lovely evening together with the kids but no mention of the fact he just disappeared during our 'free' time and didn't contact me.
Am I being unreasonable to be super offended? Can't decide whether it's worth saying something to him or if I'm being high maintenance.
