Tidy, you sound like a lovely friend. If I was in your position I think I would have told my 'friend' where to get off and then ignored her indefinitely, what the hell is it about weddings that makes women think they can be so unreasonable and spoilt? I absolutely hate weddings, they bring out the worst in everyone even afterwards. I currently have relatives who will not speak to me because I didn't put in enough effort with them, I was 9months pregnant at their wedding and I thought I'd done well just to get there and ignore the fact that me and my husband were crammed onto a tiny table with random people who didn't know each other and were far away from any of our family. It's a wedding, that's it!
I don't think theses bridezilla types realise that they have to face their guests after the big day, they don't realise that there will be consequences to treating those around them like dirt. And don't get me started on that Confetti website, Christ on a bike, talk about fuelling the fire hun.
