Also, any advice on making things less awkward at home during the transition from romantically involved couple to just friends? This is probably easier for people when the process has been a long time in the making, but in our case it literally took a couple weeks...and one of those she was gone.
I can tell you it doesn't necessarily get an easier for those of us who have been doing it for a long time. I have been living with my W as a "friend" for a few months now. What has worked best for me is to emotionally detach from her and eliminate any expectations that I might have. It is hard and I have backslid often, each time resulting in disappointment because she is clearly not interested in me anymore.
I question your decision to simply let her move 1000 miles away with your son to go and live the single life. It doesn't seem like she has your son's best interest in sight. She wants to take him from his father and subject him to nights of being with a babysitter while she parties and lives it up. If she wants to be "single" then let her be single and that means you keep the kid. JMO. Best of luck.
