Bea, How are you doing? I know that the phone call probably not only shocked you, but brought back some memories of what has transpired over the last 11 years.
I'm glad he called you and has come to realize what a monster he has been to all of you. No one knows if this is just a moment of clarity or the real deal...but time will tell if he's actually coming out of the fog of MLC. He has lost so much, i.e., a wonderful wife and great children. He destroyed a good marriage and any chances of that marriage being reconciled.
I'm very glad he acknowledged your feelings. Again, time will tell if your h is sticking his head out of the rabbit hole or if he's above ground for good.
Take care.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
