I drank and did drugs, in my opinion this was just as bad.
I don't think it's as bad as to be abusive. It is critical to, as you say, be in his life, care about him, so that he knows that there is place on earth where he is always welcomed regardless of his status, income etc.
I think I am abusive towards my kids. Patience is a key. I am not patient enough. <img src="/ubbthreads/images/graemlins/disagree.gif" alt="" />
It was good idea about the licence.
