I said this in another thread, but its worth repeating
Communication is NOT always goign to be pleasant
1. Sometimes its good news ("You look good today dear") 2. Sometimes its bad news ("Your brother passed away today", "You are cheating on me and it hurts", "I had to feel like you do for three months while you were having sex with another man... suck it up")
The adult way to handle hearing things is to hear them and NOT turn it around into an ATTACK and get DEFENSIVE.
YOU "I found your wall the car dear" HER "Oh, so you're saying I am careless!!!???"
Your wife wants to handle communication in a jeuvenile way... hearing only the good things, and immediately throwing back the bad stuff... it's time for her to grow up.
I would lead with examples of how SHE had bad news for YOU, and how you had to handle that...
This is a very subtle form of bullying, if she keeps it up, you will only want to tell her good news... and that is NOT good for a marriage. She can't bully all the bad news into the ground just because it's painful for her to hear.. its NOT good for you OR her in the long term... not to mention its bad for your kids.
