Feeling better this morning, though realising that I am in this for the long haul.
I think I've been secretly thinking that if I drop the rope and leave him alone he will come to his senses - he'll miss me, or worry that I am going to leave, or just remember that he loves me. I've been waiting, I think, for him to snap out of it.
But no signs of that. He just actually isn't interested.
