1. I just finished reading NMMNG and a behavior of your wife BB about the pets. It sound like she has this need to "be needed" and the pets gives her that.
You on the other hand provide for her to be in that position to be needed by her pets, but not yourself except for sex.
2. How well defined is your boundaries about finances and budget? This is an area where I am not yet in control of. And based on the book, it's that "don't want to rock the boat" kind of mentality. Sure I say my complaints, but I do not DO the needed action to get the results I want. That is my issue.
3. It sounds like you two are in a cycle where each of you take turns dishing out punishments with passive-aggressive behaviors. Well, from what I know about "behaviors," they are a form of communicating a need. And there are ways to change behaviors when shown tools of how to communicate those needs.
If you live each day, as if it was your last, someday you'll most certainly be right.
