I agree w/you about he suiting and quarreling...it's certainly not the way to go about making amends. I'm not making excuses, but something is definitely driving this anger now and the way he's going about seeking attention makes me wonder if he's angry at the world and at himself because his health is bad...but time will tell on that. I've see so many of them act out like this when they've been given bad news about their health over the years.
Bea, I am keeping you in my thoughts and prayers for a speedy resolution to all of this. Life is far too short to have to deal w/this every couple of weeks or so.
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.
