I think this is a very helpful conversation in that it allows you to entertain the thought that your wife's behavior is NOT, quite likely, all about you. I'm not defending it, you understand. But if you can manage to depersonalize it, you might be able to take your (natural) knee-jerk defensiveness out of the equation, which must be positive, and aid in the compassion department.
