Hey C2H: I will check out that link - it sounds interesting.
No, I would never be interested in a new R with him other than the person with whom I share kids and someday grandchildren. As we learned in D.R. - that part doesn't really change. Only with death comes that finality (I know, I know - don't go there! ).I give the kids credit for maintaining a R with a dad who never puts them first, rarely has much time for them. D has been especially good about it all. But yes - he could most definitely see them more, go on vacation, give them more $, but no - they are not the priority.
Perhaps raising a disabled son on my own has made me a bit more uptight. He is quick to judge what I do with him - but never lends any support. That's when you learn to let it go in one ear and out the other. Not answering the phone works too.
