You're in a tough position Grateful, I know you've read the other threads with As and the partner posting here grappling with all those feelings of anger and betrayal.
Some people won't get over it, they may forgive at some point but that may take a long time.
Continue on your path knowing that W has her own. Be the best father/co-parent you can be. I wouldn't bring up God's will to her again as it sounds blaming.
Move forward.

Let me give up the need to know why things happen as they do. I will never know and constant wondering is constant suffering. Caroline Myss
