Did I make a mistake? My mother is paying for the majority of the wedding. My fiance's parents have offerd to help pay for part of the wedding (but never formally to my mother until after the invitations were ordered and they haven't actually contributed anything yet). The invites were already sent out and they basically said that 'mother of bride requests your presence at marraige of [me] to [fiance]' with no mention of his parents. MIL just called to say she was 'a little surprised' that their names weren't on there. It didn't even occur to me at the time to put them on the invite... I apologized and she doesn't seem upset, but should we have worded the invites differently?
