Pretty amazing stuff Bobbijo. Not the kind of stuff that I would say WTF about, but that's me. There .. that was my 2X4. lol.

You need to commit to Zero, ZERO attempts at even thinking about anything to do with fixing Dan and pulling him out of his "funk". Even indirect means of this should be off limits. R talks surely fall into that category.

As I have been able to step back from the interaction with her, I can see that this was very contributory to the recent slide. Before I go pretending like I know so much about all this R stuff, I will leave it at that.
