I'd say that people need to go thru the 5 stages of grief:

denial
anger
barganing
depression
acceptance

This can take a long time and sometimes people get stuck in a stage and can't move past it. People stuck in a stage will revisit the problem without moving through the problem. Once someone truly reaches acceptance, it isn't so bad to revisit the "scar" since you have passed thru the depression phase already. I'm no "sykologist" but I'd read up on managing change/transition to learn more. Hope this helps.
