LO, your H is not even out of the house yet, only "first time out publicly" with OW and he is already like that. He cannot live without you. He just does not know it yet. Keep on detaching and GAL. Expect him to continue to flip flop. It is what you want to do, to take him back or not (but not just yet as you know as well as us that he will be back and forth)

Hope you had a great day with DD.
