Hi GBO - Yes, he is showing remorse, and yes, it is soothing that he sees this in the same vein now as I do - that it was regrettable. As Betsey says, we are healing one day at a time.
I am under no illusion that we are out of the woods - he will have bouts of depression, and I will no doubt have moments of bitterness, anger and hurt. We just have to be prepared for them.
Feels like another layer of the confusion has been peeled away. For which I'm thankful.
