I'm friends with a couple who are lovely people, we went on holiday and the experience revealed near constant bickering between them followed by 'making up' as we were out and about (that sounds so teen-like as I type!). Most of it seemed to be the guy picking the girl up on a dozen things - pulling her aside and saying don't do/say this and that. I seriously can't figure out what his problem was as she's lovely and good fun - certainly not rowdy, offensive or anything that would warrant bring pulled up on like that!
My issue is that I asked the girl if things were ok and I'm pretty sure he overheard me - she changed the subject instantly and he now seems to be pretty angry with me, he can't/won't even look me in the eye. I wish I'd kept my big mouth shut, I was just concerned. Half of me thinks he must be embarrassed at what he overheard but I'm also annoyed with myself for sticking my nose in AND I obviously wasn't subtle about it which may well have made things worse between them.
Lesson very much learnt but how unreasonable is his behaviour towards me? After my spectacularly uhelpful show of concern, I feel I can only wait for the dust to settle.
