If your OH agrees to go to an event with you - do you decide before you go how long you'll be there for? IMO - if you say you'll go, you should go along, whether that be a few hours or an all night affair. If you don't like the person (which he didn't tonight) you just grit your teeth and get on with it - it's only one night? Or is that really unreasonable of me? OH thinks so.
