What does Frank do next?

It was mentioned in another post that in the script in a part that wasn't filmed Frank goes back to his wife and kid. I disagree. I think Frank goes back to the life of being a thief. No attachments, no legitimate businesses. He leads the life that Robert De Niro does in Heat. When you feel the heat you leave everything behind. All Frank wants to do at this point is survive and not go back to prison.
