t-mom, hang in there. I know it's tough to not get the responses that you are hoping for here - it does happen eventually, keep posting often and you will catch someones ear (eye).
I also know it is tough to reach the level of detachment that you need for yourself while living with him. I've been trying for months to get this. Just as I feel like I'm there, some level of normal life happens and it brings it crumbling down again. I am not a very good example of what to do, but I'm still here (wish I was on an upswing).
I go through times that I want to quit it all and start over too - then I think about what I value.
What are you doing for yourself to keep your PMA up? How about your son - any extra activities with him - how is he reacting to this?
Keep up the fight!
