I want to buy a replacement car my wife doesn't approve of
That sounds pretty neat! Why wouldn't your wife approve of the car?
She's crazy. She doesn't know what I'm going through.
It would be disrespectful to buy a car that your wife doesn't like. A car is a big purchase so you both should approve of the car.
She knows I'm going through a lot and she shouldn't say that to me.
Just because you are having a mid-life crisis, doesn't mean you are allowed to spend recklessly. Your wife is just trying to look out for you, so maybe you should try listening to her side instead of ignoring her and buying it.
