I agree that none of what W says sounds permanent, and I think it will be good for her growth to actually get out and see how her life could be different without you (as hard and crappy as this is), and it will be good for her to see you GAL and that you will be okay with or without her (although we all know you'd prefer it to be with).
I would've thought that she would've brought up the need to talk with the kids about it by now if she's leaving tomorrow, but maybe she's just procrastinating and waiting until it is absolutely necessary. Then again, maybe her plans will fall through and she'll decide to stay. Whatever the case may be, you have a good grip on what needs to be done on your end and I wish you the best of luck!
