Hi Ben, I've been thinking about you, wondering how you were doing. Good to hear from you. I have a feeling your W may start to come out of the fog now that the reality of her actions are coming home to roost. Their fantasies of a fantastic new life with one or more OM's rarely come true. She still has a long way to fall though. Despite the pain I think you are doing the right thing, as long as she lived with you she would never learn to miss you and nothing would have changed. I have a friend who posts here sometimes who has been in a similar limbo for over 2 years now and his W is as disconnected from the M as ever. So rest assured you are on the right path.
And let me just say I am VERY impressed you've hit 9% bodyfat, that's incredible! I've been cutting weight for months trying to get down to 10% and it is hard, hard work! I made a run at it a couple of years ago and made it to 12% but man, at that point the weight loss slows to a crawl. I'm doing good to lose a pound a month once I'm in that range. I've cut about 8 pounds so far, 2 more to get to my intermediate goal and then another 4 or 5 to reach my final goal of 10%. I have no desire to cut more than that, it gets very hard to maintain, especially at my age. So congrats, that's really amazing!
