It is the scariest thing to think about moving on with your life without your spouse. Learning to detach is hard. How you start is by moving on with your life as if your spouse won't be in it anymore. Doesn't mean you won't, or don't want them in it, but that you can. You GAL, you act happy around them, you do things because they are good for you. I think your list is good. I had to stop reading about affairs & I refuse to google "separation" now that DH just moved out an hour ago. I can tend to overdue the "info" emersion and swim in that, instead of taking my mind off my sitch.
