I guess I've become a bit philosophical and abstract to elicit many comments from those who might be coming across this thread. That's okay-- I'm still gaining a lot from being able to use this forum to write out my thoughts and feelings.
Tomorrow, though (technically today, as it's after midnight), STBX comes by to pick up the rest of her things. This will be the first time I've seen her in more than a month-- and it just might be the last time I see her, ever.
I hope I have the peace of mind to smile and treat her kindly, and the presence of mind to say nothing more than "goodbye".
