I wonder what she thought about me getting her the books though.
I would guess, she is appreciative and a tad suspicious (but that is some serious long distance mind-reading).
IMO- you are still too focused on her. I think you should make sure you are GALing and don't do anything more than you are right now.
Sounds like she came home because she was stuck between either subjecting her child to physical pain or abandoning her kids. Not exactly a pleasant or enthusiastic motivation.
I am going out on a limb here as I really relate to your W for some reason. She needs to see what she is missing by withholding from you. You are attractive, great with the kids, have your sh*t together...you are a man only a fool would [withhold from]...
If I were her my big inner subconscious question would be "why the heck is Mr. Fabulous sticking around for this when I am giving him nada?"
So Stuck, can you articulate clearly, today, why are you still there? (this is not a trick question, just for you to be honest about where you are at today)...
