Hi lil, and welcome.
A LOT of what you said sounds familiar to me. My H and I used to drink together a lot. I don't have kids, but eventually I started to grow out of it. It just wasn't that fun anymore. I kept thinking he would too, but it never happened and only continued to get worse. Mine also has 2 DWIs, and continues to drink and drive. Worse, I've seen him passed out in his car with the engine on more than once or twice. I also just don't "take" whatever he deals me...if he's trying to manipulate or control me, I am very vocal about it and refuse too! All this to say, I understand EXACTLY how you were feeling. It sounds like you did a great thing by taking your son away from that environment. Not to be a downer, but I know from experience that mine was capable of stopping for a short period of time in order to convince me things would be different. When I would let my guard down, he was back at it full force. So be careful with the 2 week thing.
