Congratulations on getting work lined up so quickly.

Your husband might temporarily show some interest because you've moved out of his control - but just because he wants to keep you on the hook as Plan B doesn't mean he's become the man he should be. Nothing less than a year of individual therapy for him before you should even consider dating him (and he won't do that because he's a selfish jerk who wished his daughter had never been born).

Enjoy your friends, your work, your support group. Don't worry about your H. You did the right thing for you and your daughter.
