Wedding are boring, including my own, I have no wish to attend anymore.
Boring to you. Some weddings are boring, I agree, but not all. If you are at a wedding of someone for whom you care, which is cheerful and pretty, it's not going to be boring.
I've been to many weddings, can't remember how many. I've had a good time at many and enjoyed the day.
As for the current fashion for weddings abroad, they're for people whose guests can afford it. Most of them take place at home and the best of them have reception at parents' house (& garden). They can be great fun.
Civil partnerships may well be boring, I've never been to one so don't know but can't see they will be much different to civil weddings. Siblings, relatives or friends who live together long term (and I agree they should have civil partnerships), aren't likely to have a big do with reception, it will be a private matter.
