TOH, I have been following your sitch for a long time....you have been given LOTS of great advice by both A New 2morro and Bill; but, you don't follow any of it.
You are still centering your life around your H and what he is or is not going to do. You have got to find a way to move on with your life, without him. Maybe then, he will see what he has left behind. As long as he can have his cake and eat it too, this cycle is going to continue. You have got to find a way to put your foot down and set some boundaries. I know it's not always easy; but, you might get surprised.
