You are living proof that "God makes all things work together for the good, for those that love Him, and are the called according to His purpose." I don't believe He CAUSES bad things to happpen to good people, but of course we all have "free will" and He CAN, and does, USE these things to make us stronger, IF WE ALLOW HIM TO.
End of sermon.
I commend your courage. I commend your faith. I commend your heading straight into the storm.
You will be better for all of this, regardless of what your confused wife decides to do.
