What I have noticed with my daughter is that she did admit to her drug use readily at the beginning of her addiction. As her addiction progressed so did her ability to lie and hide it. She denied her everyday use of vicodin and oxy for almost 7 months. I, like you, knew that she was using but she denied it vehemently. Finally admitted that she had a problem. She did that because she wanted me to bail her out, not because she actually wanted help. So because he has been honest in the past does not mean he will be now. His addiction has progressed and he wants to protect it at all costs. Taking care of yourself and protecting your finances is about the only thing you can do now. Denying the obvious only keeps you stuck. Hugs, Marle
