FOBD, you sound like you are doing great today, good to hear!

I just want to throw out there, if you did decide you want to mix things up and not help her pack this time, you could do it without coming off as a jerk who does not care. If you smile, act polite, and simply state you have some things you need to take care of while she packs up her things, I don't think she'll see it as the "old FOBD." It might be a risk though, I see that. You know better than anyone how she might see these actions, and you know the best route to take for you.

Happiness is not something ready made. It comes from your own actions.
