Being a man, I can not begin to understand the pain and ambivalence you must be expeirenceing, but I do know that God cares deeply for you. Tumult and pain happen even to those in his will. This is not a sign he has abandoned you or will abandon you. You are still a beautiful whole women. Never forget Christ's blood cleans us. It is never anything someone else may do to us that determines our "cleanness" in his eyes. You are right in not blaming the child. Please believe, she is a victim in this as much as you.
As others have said seek out strong Christian counseling, pray often and sourround yourself with the body of Christ. I will pray for you.
