My W dumped on my sister on FB, too. Every time W tried to make fantasyland statements and thoughts, my sister countered it with reality.
The transcript was really quite telling of my W's POV and where her thoughts are.
You know what? I don't care. I worry about where my thoughts are. I worry about what my actions do and how the play into real life. My circle of concern has grown smaller and my circle of influence has grown to be more refined.
Keep your eyes and focus out in front of you.
