Addiction is a progressive disease and usually gets worse over time.
If he is still in denial...and making you think that you're the crazy one...it's unlikely that he will be willing to stop any time soon.
I agree with the others to protect your child, and protect your finances before they are all gone.
It's a sad and painful experience to watch someone we love self-destruct. It is sadder and even more painful when the entire family has to suffer because of it.
Please take very good care of yourself and your child.
