I think honeypig nailed it. Seems like he wants to keep his foot in the door but only as much as it suits him which is not fair to you and particularly not to your kids. You all get your hopes up and then he fails to deliver.
Sorry you're hurting, it's hard and I agree he sent mixed signals. Therefore it's best not to count on him for anything.
