My line sister has been planning a big wedding. Total cost of nonrefundable items:
Wedding dress $2000
Photographer $1000
Caterer $3300
Invitations $1200
Flowers $1000
(These are just the expenses I know about)
The wedding was scheduled for the 20th(Saturday). Well, Friday (the 12th), the groom to be decided that he does not want to be married and that he just wants to be friends

(They have been dating for ten years) My question is, in your own opinion of etiquette, what is an "acceptable" time period for calling off a wedding?
