I can understand how you feel and the pain you are going through. However, you need to drop that rope because it only continues the pain. I am not telling you to drop the rope (hope that someday you will be back together) but the rope that ties your happiness to your WAH. Create your own happiness, you are responsible for your own happiness. Make yourself into the person he would want to come back to.
