Like many of those here, my h has called a halt to the divorce proceedings twice already.
Not only are they seeing an external fix with the divorce, but for many, it seems the process itself takes on a life of its own. He has paused it twice, and then restarted it, because as Snodderly has pointed out, he is still reluctant to do the work required to sort out the marriage and himself. However, I do not think he really wants the divorce. I think he wants to wake up one morning and find that everything is Ok.
Because that isn't happening - I call it magical thnking - then divorce seems like the easier option, in theory. It is the practicalities they don't like, like providing the documentation, and being questioned by the judge about what exactly happened to that very large chunk of money, and so on. It is about reality which they are still avoiding.
