I don't think that Frank made it clear on the boards until recently that he is, indeed, working on himself.
I think the reason he wants to know what's going on with his wife is that he's a human being and he still loves her. And no matter how brave a face any of us put on this or how much we have detached, if there's a shred of humanity left in us, we weep, we have regrets, we still think there might be an angle in to our spouse's heart. Sometimes we are afraid and we want to know what our spouse may be plotting/thinking. Trust has been eroded.
You know this Jeff.
And you also know that trying to figure out what's going on with our spouses is, largely, a fruitless exercize.
But, still, we all want to know what our spouses are thinking. Do they still love us? Is there hope? What's REALLY going on inside there?
