Jon, I think that you did a great job. You handled things maturely and lovingly.
I think that I read in DB/DR about how some couples end up taking classes on how to communicate better in order to be better parents and then decide not to divorce. To me, that story implies that they begin communicating about issues that have stood between them. It looks like you and your W are communicating about things in a respectful and validating manner and I imagine that forgiveness and healing can come in behind those conversations.
