Don't get down about her wanting to move in with the parents. Even if the past little while has been great, it's surely waaaay too soon for her to think "In 2 months everything will be fine so I'll just move back with B."
And moving in with the parents is really the best result besides coming back. She can move away from there at any time, it leaves her options open--maybe after this extra 1 or 2 months she will be ready to recommit, who knows. Anyway, it's much better than re-signing for another 6-12 months in her apartment.
Have a great date tonight!
