Was at close relatives wedding earlier in the week, just for immediate family because of budget restraints, was a lovely day, no problems.
Tonight is their bigger party/reception for wider family and friends which we have been looking forward to for ages, (more thsn the wedding lol). Unfortunately last night I came down with d&v and was up all night, I’m knackered and in a lot of pain with cramps etc, my husband thinks il be fine in 8 hrs and should man up and go but I think if I’ve got a bug I should probably stay at home and not infect others?
I know I’m right btw but I’m going to get a lot of flak from him and his family if I don’t go 
Aibu?
