I am sorry you are dealing with this. Unfortunately, it is not uncommon. Many a family has been divided and even destroyed by addiction. While we cannot tell anyone what to do, we can gently suggest that you keep in mind that you cannot change anyone; not your son, your wife, your daughters, or anyone else. The only control you have is over yourself and how you choose to deal with the situation at hand.
I haven't delved into your blog yet; I've only read the first and last entries, so I don't know if you have answered this question, but, have you considered attending alanon meetings? They can be a great help in learning how to detach from a situation over which you have no control. I hope you will consider it, and I hope you are able to find a way to get some peace and serenity in your life.
