It is soooo difficult tuning out the negativity. I've never been real good at it.
One time though, I took to tape recording my ex (before we were ex'es) and played it back for him when he was in a more receptive and better mood. He honestly couldn't believe he sounded as negative as he did. It was an eye opener for him and he really did try to be more postive after that. After awhile though, I think his depression just took stronger hold of him and he just couldn't fight his way out of a wet paperbag
I hope you can find something that works for you Susan.
