Its not about being the "dutiful wife" its about making a decision about whether to reprieve the weekend, which yes, he has potentially spoilt, or whether to store and talk about it at a more appropriate time. IE - not when a four year old child just wants to see her daddy, how pants will it be for her if her parents are rowing all weekend.
I'm not saying let it go full stop, he is behaving like a cunt, but its not like they have all the time in the world, just the weekend. Saying that, you don't want it to fester either - but big blow out row - the one i would have it i were the OP, because i never follow my own advice i don't, is not the way this time.
