Princess, he is an active addict. It is a dark world active addicts live in, dark and deceptive and it will suck your very soul out of you if you let it.
Not one word he says points to trust or recovery. How do I know? Because I have heard all the excuses, lies, can't do it of you won't help me's, and manipulative words from my own son. Just take a good read around here and you'll see that most of us had to learn the hard way, just like you. But we did learn and when we knew better we did better and stepped away from the darkness.
Please get help for you. Al-anon, Nar-non and CoDA are 3 similar fellowships that can help you put your life back together again.
The choice is yours. If not for yourself, do it for your child.
Hugs
