My W does this as well; and the dark period usually ends with her reaching out unexpectedly. So stick with it - you've had some positive connections, and sometimes the baby steps are excruciating, but hang in there.
Someone once said - imagine being in a car wreck where you had to re-learn to walk. You've walked your whole life so imagine how frustrating it would be to try to tell your legs to do what you KNOW they can do. But instead you have to try to get 1" of pure agony. You feel like giving up, but the next time maybe you get 2". A couple weeks later, maybe you take two full steps. But you can't get your legs to do what you want, unless you're patient, only push them to do what they can do, and when they need a break, let them go.
