Hey Scott. I'm sorry you find yourself here but keep posting, keep listening.

There's a lot of mind reading in your post....recognize it and try to avoid it. You can't know what she is thinking and questioning it over and over isn't productive.
I think you dodged PS's question...whether intentional or not. "Why?" was the question. Dig into that...its the starting place.
