For context: I got married 3 years ago, saved up for a couple of years to be able to afford it, tried to keep it simple and made all decorations, wedding favours etc. Was a lovely day and all had a good time. Overall cost was approx 5k including what I estimate my parents spent on drink (they offered to contribute this).
My aibu: Dsis is getting married in January to someone from another culture. In his culture the groom's family pay for an event and the brides family do. Basically my parents are funding her entire wedding in this country so that she isn't embarrassed in front of her in laws who are funding an event in their country of origin. She is not very focussed on cost (although my parents aren't letting her take the piss either) and isn't going to put the effort in to make stuff herself to keep costs down despite being very arty and creative. In addition to this we have inherited money in the last year from death of a relative so she could easily afford to pay for it herself! Am I just being a jealous cow? Think I also feel that she thinks my nice simple wedding not good enough which is making me a bit sad!
