Craig, I'm in a similar sitch. My D was final(?) in October. I question anything as being final as I would never have thought I wouldnt be still married to my best friend. So on the other hand, since circumstances make it appear to be over and general consensus would be that it is over permanently, I have decided to continue being a father and a husband (without the obvious external signs) and pray for her, my children and myself.
Praying for you too, Craig.
