Portia, Your SO, like all mlcers, thinks that we will always be right where they left us, while they are out exploring the world. They can't see beyond their own little world that we are steadily moving on each and every day and that one day, we will be gone. Life doesn't stand still, nor should we.
I think it's time your SO face some of the consquences of his actions and I'm very glad to read that he's going to be speaking to his counselor about this.
Portia, it's time you take care of yourself and find a way to enjoy life again. If he truly wakes up and wants to be w/you, he will find a way to do it. But, until then, live your life as if this will never happen.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
