Accepted invite initially.
We were provided with menu choices couple of weeks before the wedding and told to get in touch with caterers directly with any dietary requirements.
They could not guarantee that I would not be exposed to allergen (life threatening) and could not offer alternative. AIBU for not attending on this basis only? I would feel v. miserable watching people have a lovely meal I could not have.
Venue in the middle of nowhere so nowhere to pop out for a quick meal.
