I just want to make a short comment about TxHubby having a successful in-house separation. I disagree. He did not have a successful in-house S that led to reconciliation. In fact, it was so bad it led to him becoming a WAH! (I responded to him when he posted about it). He was fed up and walking away from his WW......and that action is what led to a reconciliation (if they are still together). I have not read any updates or seen him posting lately.
So, I don't think we can give credit to the in-house S having anything to do with his WW's change of heart. It was the fact he was done.....and leaving her, and she knew he meant business.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
