I'm glad you got legal advice, and VERY glad that what you signed won't hurt you.
As for your wife, it's not that you're putting her "out of the picture," but rather you're putting HOW SHE FEELS ABOUT THINGS, AND HOW SHE WILL REACT out of your decision-making process. She can still be very much on your heart, and WILL be, but you simply must remove the "will this make her angry?" from your strategy right now.
Replace it with "What is the RIGHT THING TO DO here? What is best for my children? For me? What would GOD HIMSELF have me do in this situation, if He were standing right in front of me?"
Sorry for the 2x4, but I was very worried about you legally.
