Wow. How do I answer this one? And to Phyl, no less.
Sometimes, people learn too late that the path they were taking was not the one that leads to where they wanted to go. The path was the easy one, all down hill, no sharp turns. After a long while, they realize their mistake and turn around. Guess what. The path now is all uphill, with no alternate paths available. One of the uphill battles is having the courage to reach out to people who you (they) have hurt in the past. Yes, part of the motive may be to make themselves feel more at peace, but perhaps it's more than that. They can't make the journey back to the right path without re-tracing their previous path.
Phyl, maybe trying to put yourself in their shoes would help? Reach out to them and offer support and understanding. Forgive them for the past, and see what happens from there. At least then you will know you did what you could to reconcile. If you don't give them a chance, will you end up regretting it later, wondering if maybe you should have tried?
