before i start i want to say my DH is really lovely and has bought me flowers because i was upset last night but he doesn't see that he's done anything wrong and although i'm not annoyed anymore i want to know if you think IWBU to be upset...
so, i do some voluntary work, i do enjoy it but it involves hard work and responsibility for other people's children.
last year, we had a weekend away - me in charge of lots of kids, very hard work, voluntary and rewarding but not exactly a 'holiday'. DH couldn't bear the thought of being left alone all weekend so arranged a weekend away with two mates, which was fine, but he was an hour late picking me up after my weekend and i was waiting with my kit by the side of a road in the dark as everybody else had packed up and gone 
this year, i said, for goodness sake leave me the car! so he has, but he emailed all our joint friends to say he was being left alone and did any of them want to go away with him an they all said yes
so now all our joint friends and him are having a long weekend away (longer than my trip). i said i was a bit annoyed about this as it would probably be the only weekend away of the summer that 'the group' could all make and he'd deliberately made it the weekend i was busy. he thinks IABVU and that he shouldn't have to sit at home alone.
So... AIBU to be upset and feel left out???
[for the record, he has now bought flowers, i have stopped being upset but still think IWNU to be upset, and of course they're all still going]
