NC. Broke up with emotionally abusive partner. He smokes cannabis. When we first got together i didn't know this and it's something that has progressed and is now a daily habit throughout the day. He is moody, lazy, mostly like to sleep and relax probably because he's stoned so not much conversation of an evening, he seems depressed. I think these are side effects from smoking and think he should quit. He says it's part of him and who he is. I feel a lot of our problems stemmed from this. He wants to be together but refuses to stop his daily habit. What would you do?
