I feel that he has gone to far in his own mind, and he has had to leave a relationship/old life due to things in his life, choices he has made, and he feels that he cannot go back. Even if she wants him back and wants to work it out. He feels it's better to move forward from this point because there are still so many unanswered issues in his life that it's still spinning out of control. "The line don't be gone, don't be gone for long" was what my ex told me, but I was in the same place that he is in, and looking in the review is nice, but you can't turn back. To much hurt, and to much pain to do it again. It's easier to drink the memories away then have to face them. But just my opinion.
