I just read "Advice for spouses of Walkaways" from Nicky in the archives - I understand what you mean, Rob, but that guilt isn't easy to dismiss. I guess it's easy to say both of us should have read DR or went to counseling, etc., and you'd be right - but the fact remains that I've only just begun to feel the pain to the depth that my wife has for a long time. I think women allow themselves a lot more emotion than men, and define things much more quickly. I'm not going to make any excuses, because much of her pain was hidden by her anger, but I should have seen it. My own depression symptoms clouded everything for me, making it seem like I was on the outside looking in, helpless to change what I was seeing.
No matter what, I'll keep working on myself, if only to feel better and benefit my son and our relationship. Thanks again to everyone out there.
