You have good evidence, however your husband moving out before I-751 approval and no official divorce will make this:
very improbable. Most likely, decision won't be made. The IO will likely advise converting petition to divorce waiver and issue you RFE to provide divorce decree. You probably need to withdraw your N-400.
Have you consulted an immigration attorney and family attorney? Your situation is not end of the world, but you do need to have a solid plan to make it work. Sometimes that involves postponing interview, filing for divorce etc.
