KLM,
Your story is very familiar. It sounds like me. My AH answer to quitting meth was to bring home a GIANT bag of weed. I thought fine. If this gets him through. Guess what it didn't. He just smokes that when he is crashing and he HAS to sleep. He doesn't come home for a week at a time. On 5 different occasions that i can think of, I also told him to move out to the camper. Then he roles in the back door after being gone for 4 days and is like "hi honey, i'm home" Like we never had the conversation. Unfortunately we have 3 children at home and i feel like at this point I am being FORCED to move out just to save us. I am in the process of planning this. Although I don't want to live in that house regardless.... I don't know what is "hidden" I have found plenty before. He is just more sneaky now. Good luck. stick to your guns. I know that is easier said than done...trust me...
