Sending some hugs to you and remember that your son is just doing "what addicts do". To try to understand his behavior is useless. To try to understand why your parents keep going to bat for your son is also useless. The only thing you can do is let go and I think you are doing a good job with that part. Your ex has been there and so maybe he is the person who can get through to your son. Lord knows you have tried enough times. Prayers for everyone involved. Hugs, Marle
