HI, Ed, Haven't posted on your thread before, but found myself reading this entire thread.
One thing is very evident--you really love your W despite everything she has done/not done.
Having said that I agree w leo...she needs to be held accountable for her actions/lack of actions.
I would ask her for a meeting to refine her role/visitation in her son's life. It sounds like she is trying to find her way out of the dismal life she has for herself, but it may actually be wishful thinking between nights out at the bar.
I agree also it is time for you to let her go/drop the rope. I know she determines when / if she sees your S, but YOU need a life for YOU.
It sounds like you were finding some good GAL activities, outside of your S's activities, but you need to pursue MORE and more frequently.
It will make you stronger. It will motivate you to want to do more and expand your social network.
You deserve more in life and so does your son. Stop waiting for her...just my two cents.
