Thanks, MB and PL. I'm with you, PL, in thinking that my W will ultimately not want to file. She is in agony because of her sin, and I believe that she knows that committing the biggest sin of her life is not what's going to make her happy.
Something else I forgot to mention. D4 knows that "Mommy doesn't want to be married to Daddy anymore," but I always speak well of W in front of her. Yesterday, though, D$ shocked me by saying, "I'm going to tell Mommy to be your wife again, or I'll hate her forever." This girl doesn't hate anyone; she loves everybody and is always happy. I told her that was wrong and her Mommy loves her very much and she needs to love her back.
The LORD is near to all who call on him, to all who call on him in truth." (Psalm 145:18)
