I don' know, Kikki. I really don't know about the hurt. Short or long term. To be honest former MLCers I know don't seem to have that much hurt, or to have been throught that much hurt. . It is their LBS who has the hurt.
The MLCer seem to tend to regret what they did, usually because, in the end they end up with someone far worst than the LBS or alone, or because the LBS moved on without them, but hurt is not something tend to notice in former MLCers.
More regret from what they lost, or no longer can have. In a way, it is if the MLCer will always be selfish. They regret what they lost. Or they are glad that the LBS is still willing yo take them back. It always seem to be about them.
Sometimes good things fall apart so better things can fall together. (Marilyn Monroe)
