It's possible (probable) that he had developed a fear of rejection due to his divorce, but the very fact that he had a divorce indicates that he had been able to date and marry in the first place (to a poor choice, no doubt). I'm sure that his approach was able to return him to where he was before, and perhaps improve him, but I wonder if it would be any good for someone with a deep-seated fear of rejection, or if it might not make things worse (perhaps due to a few scenarios ending poorly, or the subject finding himself unable to complete even the simplest ones, and retreating further into himself).
