suckerpunch, I am pretty much in the same boat as you and I know exactly what you're going through; my wife took off and has not looked back at all. I long and ache so bad for my wife, I would do anything to have one more chance with her.
I'm chalking a lot of the difficulty I'm going through to the holidays and shorter days (I have Seasonal Affliction Disorder), so I'm trying to be kind to myself, get a lot of sunshine (mornings in front of a large window, walks if weather permits), and exercise. Remember it supposedly takes half the life of your marriage before you are fully healed. Forgive yourself for your feelings, because there is nothing wrong with wanting to reconcile with your W. Be grateful you are not one of those small people who has given into bitterness and anger. Rededicate yourself to GAL, that's for you! Realize that you have already traveled far, learned much, and grown tall. Remember you will have good days and bad days, particularly this time of the year. Do know that you're not alone, and we will be here for you.
