I am in a similar situation but my wife won't talk to me. I have also heard of people getting back together after papers are filed but before D is final. Also after the D. As far as how many? I wish I knew. I am holding on to hope but I try to put it in the back of my mind. IMO you have to act as though you know the divorce is going to go through and be the best possible man you can be. I know it stinks. Hang in there. I wish you all the best.
