It seems to me that you are still focusing of HIM and allowing him way too much power over your thoughts and emotions.
If you could really let go and GAL for you and your son, and just leave H sitting there, like nothing but another piece of furniture in your house, then I would say to leave the decision to stay or go in his lap and don't react either positively or negatively no matter what he does!
However, it appears that you may have reached a point where you may not be able to do that (and believe me, there is no shame in saying "enough is enough"!! I could never have made it as long as you have!!!).
Only you can make that choice, BM. In my opinion, it is impossible for you at this point to make a wrong choice! As I have said, from my own experience, seperation was a good growth thing for me, and I don't think I could ever have reached the point I am now in letting go if we were still living together.
You know I support you whatever you choose!!
