Keep up the GAL to detach. If you start thinking about him find something, anything to do to get your mind off him.
Another note, with the WAS it sounds like the do a lot of cake eating, regards to LBS so they can keep them on plan B. Well it sounds like your H doesn't have OW, but he is cake eating. He gets to run off and be a bachelor then when he chooses he can come home and be a parent, H, etc. Sounds like he gets to use you to be his emotional punching bag.
