If lots of people are invited to a wedding, it can't realistically all be about 'her', since it's impossible to expect guests to not have their own thoughts and opinions that are not fully identical.
It's pretty common in fact for major family disputes to be resolved, or begin, at big weddings that only involve the bride incidentally.
It depends how much energy you spend giving into all the family dramas. Who wants to sit with whom. Who will have this reaction meeting this one, but not that one, who has what expectations in general ... but who cares. It is our wedding, not theirs.
We so far have postponed the big wedding, but when we do, the idea is to have a place big enough, food, drinks music. Fun place for the kids. Everyone invited. And then people can enjoy it, or not. I plan to be on the dance floor.
