Don't get me wrong, nor be hard on yourself about detaching. You are looking at the poster boy for "Detachment-Failures" I think out of the core DB principles... GAL, 180, PMA, Detach.... Detachment is far and away the hardest and add in a multiplier if you have children, it's brutal and feels like the exact opposite of what one should do .... Especially for us guys who receive the " you were never there for me"
Keep in mind detachment is not done out of punishment ... Nor is it an overnight thing, look at it like a weight loss program, you aren't going to chop off your own legs to lose a quick 50lbs, how do you do it? Lifestyle change (GAL) and keep at it... Slowly and consistently ... This is why the GAL portion is so important. Once you do start getting the hang of detachment your W will feel it and test you to no end... Yup, it does not get easier
Another thing, you have to work on yourself a bit... It's all fresh and new but start thinking about this... Not specifically the top ten list your wife has that is all wrong about you, but things you would like to change now... Start small, I'm here to tell you the smallest changes launch into the big ones , this time-out you've been given you can do one of two things.... Fixate and obsess about your w and what she is doing... Or build a better you, you honestly only have the power to do one of these things right?
