I agree with the above. Cocaine IS evil (I'm a recovering crack addict), and I've seen people deny it, even when there is still cocaine around their nose.
Kitty's right...you need to focus on you. Is his behavior acceptable to you? I've heard "we teach others how to treat us" and "we get what we tolerate" and I totally believe it, whether addiction is involved or not.
Please focus on what YOU want out of this relationship. You deserve to be treated with respect, and you have every right to not trust what he says...most of us addicts gave every reason NOT to be trusted and we don't gain that trust back until we've shown, by ACTIONS, that we are worthy of trust.
Hugs and prayers!
