The more I read on here (and, granted, no-one is going to be on AIBU about their perfect wedding), and the more I encounter IRL, I think that weddings are an enormous source of stress and unhappiness.
For eg My DN had a lovely destination wedding in September -( it cost a lot for me to go and my family stayed at home). Two days ago she announced she'd met someone else and was leaving her husband. It now appears that the wedding was a band-aid.
So many wedding that I've attended, have ended after a relatively short time. What on earth was all that fuss and expense about? All the family and friends wishing them well, supporting them in their relationship.
On MN - worries about money, invitees, cf bridesmaids etc.
AIBU to think - just don't do it? Go to a register office and make your commitment legal in private.
