This isn't necessarily a boomer "I hate my wife" meme comment though, right?

It's healthy in a long-term relationship to discuss things with your partner before doing them. When you communicate healthily, there are quite a few things you wouldn't just spontaneously decide to do without talking to your significant other. They might have already made plans, they might need the car, they might not want to do the thing but think you should do it, they might remind you that you're saving for a house deposit or a big trip, so on and so forth.
