I've taken my old friends advice to mean very much what you describe as the DB approach.
My wife and I haven't talked about our relationship or marriage since the day I moved out. We talk about the girls and about projects that she is working on (she works for me, in my office) but nothing really personal.
We are coming up on 3 months now. I work very hard to be happy and confident around her. I've started going out with people, attending events and actually feeling a stronger connection with people than I have in my whole life. Which is great, because it makes acting happy more like being happy.
I am know a t the place that I see it is going to be a long time before she and I are together.
