Oh Nicole there is so much wrong with your WAH right now, bailing on his family is just a consequence of his other problems. This is not the time to reconcile, even if he comes back it will be out of desperation not out of wanting to fix his mistakes. If the full time job offers you financial stability the take it without much delay. Having financial independence will give a great sense of stability to you and your D, what your H will offer for family maintenance once he gets a job is just an add on. Time to just take the bull by the horns and live as if there is no help from him emotional or financial. He can get whatever help he needs and fix his own issues, you have enough on your own hands
