Ack about the wisdom tooth! That's gotta hurt a lot. Hope it heals quickly.
You've done good work girl in restraining yourself from initiating any R talk with W. Keep it up. How wonderful that your sisters will be visiting you. I have three sisters and I know exactly what you're talking about. Something special about this kind of sisterly bond.
It appears that W's life isn't going well at this point and you have no control over that. Let her spin and eventually her rose-colored glasses will spin off as well.
