I agree with fig, he's full of crap! I think that some men are more afraid of facing their issues then doing something that would make them feel better.
I so can relate to your wanting husband to come home and you accepting him no questions asked. We all think in the beginning that if they would just come home we could fix this, but it never was about what we did or didn't do, not really. Unfortunately it's not until much later that we understand. Sometimes I really don't think that there is any right or wrong way to handle this. He would have found something in almost anything you said to get angry at you for.
I'm not saying that these things don't ever work because I have heard stories of marriages that have. People over in MLC seem to think that the WAW will just work their way through the magic tunnel. That's baloney. This is their personal journey and it takes years. After 5 years I am just now starting to see some consideration from my ex.
First off, I don't know if you know this or not but Hearts Blessing who came up with that timeline did not have a husband in MLC. Oh I wanted to believe that there were definite similarities because it meant that happy endings were possible. In fact her husband was only distant for months not years and I'm not sure that he ever did move out. I know he had an affair but you don't have to be in MLC to do that.
