As someone who left a marriage a couple of months in (for a very valid reason) I think this is a little harsh! It’s not about you, they were probably trying very hard to make things work and it very sadly didn’t work out for reasons that you surely aren’t fully aware of.
admittedly, I didn’t ask for cash gifts off anyone, in fact no presents, but my parents had contributed as had his. The couple probably are mortified, as I was, but that’s not some thing you go round talking to every guest about, and you don’t know the situation re the gift. Admittedly the family sounds a bit casual about it but again, privacy - it could be easily have been something quite serious (as it was in my case) but they don’t want to tell all and sundry.
This is the sort of judgement that makes people go through with weddings when they probably shouldn’t, by the way. It is pretty difficult to call things off at the last minute when there are so many expectations, and people’s expenditure, plus deciding to end such a serious relationship is obviously not simple. In my case, it was only totally clear I had to leave once we were married, for various reasons.
I have spoken about my embarrassment to a few of my very very close friends - this is not something I would talk about to everyone - and I’m really glad that they care enough for me not to have taken this view!
How long would you say an acceptable length of marriage was, in exchange for your expenditure??
