@juanmanuelfangioii I respect my partner, but just as I would never tell her not to buy anything expensive if she wishes and can afford it, I expect the same from her.
We have a partnership as well, but neither of us controls the expenses of the other.
I find that a lot of men will bend to their wife's complaints about how systems or components look, but have no say if their wife has 60 pairs of shoes or picks ugly furniture :-)
