As much custody of your daughter as possible. If you end up moving to another state, you take her with you. Your W has to provide child support and contribute to that ivy league university.
I would still want the facts presented with a good lawyer, somehow. The "best interest of the child" is YOU, the guy who kept his promises and upheld the best interests of your daughter through an impossible time.
What does your lawyer say? I suppose you have your "goal" based on what he/she has advised.
