You sound better than when I first started posting to you, HH. I love your "thread of hope" comment . MUCH BETTER.
I would like to "caution" you against having ANY expectations of your wife. No expectations = 0 Letdowns. It's just a wise rule of thumb.
I'm glad you were able to make it the Father/Daughter Dance. Sorry for the drama brought on by your wife, who definitely thinks the world revolves around HER at this time. Expect more of this behavior.
All right enough pussyfootin' around here...
The issue of alcohol abuse.... If she is not trapped in an all out addiction, she soon will be with such indulgence as there has been lately. We already know she has an addictive personality from your post. She's just not being very smart...and this is going to determine how your sitch turns, HH. You can't DB if there is an issue of substance abuse. I hope this does not aggravate the problems you already have.
You are setting boundaries (every other weekend with kids). GOOD FOR YOU. Now just stick to it.
