Yes, I think that is a good plan. If she does not want a divorce she will have to show it soon. You are making a stand and dropping the rope, as they say around here. If she does change her mind, then you will have the opportunity to say that you will stop the divorce if she goes to Retrouvaille with you. I know that you have been saying that you wish she would do that. So you will see. If you are giving her what she wants with a divorce, then the divorce will happen and you will go on to have a happy life with someone else. If she decides she doesn't want a divorce, then you can insist on Retrouvaille and change in the marriage. Either way your life will improve.
Yep. This is the gameplan for someone in CTH's (and my) sitch.
Lotus, I know you are a big fan of Retro (and from reading about it, I think I would be too). But, whether its MC or Retro, don't you think that the WAS has to at least be open to discussing and considering reconciliation for those methods to be effective. And I'm not talking about being effective for learning co-parenting or communication. I'm talking about effective for reconcoliation.
Not trying to pick a fight, but I know from speaking to others here that went to Retro with a WAS who really had no intention of reconciliation, and Retro/MC was a train wreck.
