More of a WWYD than a AIBU.
I'm very introverted and having a busy people week at work. Went into the city with DH last night for a walk and a drink (though I'd have happily stayed at home as well) and bumped into some friends (mutual but more DH's friends than mine). Ended up going for drinks and dinner with them.
In a nutshell, was very hard for me but didn't want to complain or drag DH away as he was having fun. Couldn't go home without him as I was the driver, but retrospectively is quite obvious that my behaviour in the group was inappropriate, as everyone was having a fun time and I was so quiet and probably spoiled it all a bit.
So WWYD in a situation where you can't leave, but really don't want to stay?
