you had a choice recently about fixing the car, right?
Your options were: 1) fix the car - she gets mad that you don't think she can take care of herself and you won't give her space. 2) don't fix the car - she gets mad that you're so lazy and don't care about the kids.
So the outcome with respect to your wife isnt impacted by your decision right? No matter which option you choose, she will be upset about something. So why are you basing your choices on how it will impact HER?
If you think that choosing the choice that will make her "happiest" is the best course of action, you are headed for a lot of disappointment.
