I don't mean replacing something that's broken/on it's last legs or something that was never in the house and being bought for the first time.
More like, one partner wants a bigger bed, a comfier sofa(i forgot to include household items in the title too) , a nicer TV, a bigger fridge.. things like that and the other partner buys they for Christmas/birthday,especially if the wishes are expressed around that time.
YABU - household items/appliances are not gifts and it's a lazy/disrespectful/horrible thing to do.
YANBU - if it's an expressed wish then it counts as a gift.
