For me it seemed to turn around when H started seeing a T. We had talked about that before and he had always been against it. Once he left, I did the drop the rope thing, I didn't call, email or contact him except for a card in the mail every two weeks or so, just so he would know I hadn't given up on him. We had daily contact because of the kids, but I tried to keep it light and short. I think once he left and was still unhappy and I was pretty much out of the picture it hit him that perhaps it was something else that was wrong. He said that he and T talked a lot about what is important in his life and to prioritze. He said when he first went in she asked him his priorities, I was #4, I know kids and work came before me, I forget what the third was.
We still have a long way to go, I don't feel out of the woods by any means, but sure am enjoying the good days! I also think the two weeks the kids and I were away visiting my sister helped with giving him time to think.
