My advice to you at this point would be to think long and hard on these two things:
1. What are my short list of dealbreakers -- my "Boundaries of Personal Integrity" -- that I'm going to want to communicate to my husband if and when he DOES ask me "What will it take? I'm willing to do what it takes!"
2. UNTIL that happens, what are my boundaries for this period we're in right now, when he's living in the house again, yet not fully committed to the marriage?
I don't have any magic answers for you on #2, and we can discuss #1 if and when that day presents itself again, but these are where I believe you need some laser-like focus.
