Go to your room, it makes easier to detach and it gives him the space he wants. Take a long shower, take care of yourself, lay down, close your eyes, sleep, rest or listen to some relaxation podcasts. Read the thread on detachment (I know I am obsessed about it but it's was lifesaver) and the one about the distance/pursuit. I will be here for you, dear H is ready to sleep, my kids are having fun at their friends' places. I am enjoying my glass of wine...
One day at a time.
