I really like your late night ramblings. There is almost always something therein that I can relate to. I feel a weird combination of resigned, lonely, hurt and numb. I don't know about the experience of your W. or mine re: the throwing of self into work. I never seemed to have success with that strategy. On an intuitive level, it seems riddled with all kinds of problems even though on the surface it appears convincing and "successful".
Keep on posting. I'm nowhere near where you are with things, but I do feel like a fish out of water.
