I know that some people above said that pot isn’t a big deal, but when you’re an addict…. you should be staying away from ALL of it, even alcohol. This is coming from someone who’s had issues with substance abuse in the past and has some time sober. It doesn’t make me all mighty and awesome, but I can definitely see why he is the way he is. Sometimes if people don’t find constructive things to do after they’ve given up an addiction, they find other things to replace… such as the hoarding. Such as the pot smoking. Such as a woman. It was something else that still eased him away from his pain. I’m not justifying his behavior at all. It sounds like he was still suffering, despite giving up the hard drugs. Unfortunately, you were a bystander in this. He still had addict tendencies like manipulating you and making you feel guilty for things you didn’t even do. It will happen for the untreated mental aspect of addiction. He won’t be able to endure a healthy relationship until he works on himself…and it sounds like he has A LOT of work to do. As for you, don’t be upset that you were with someone like him. Perhaps you saw hope, you enjoyed his company… and of course people don’t always end up as they seem during the initial beginning together. As hurt as you may seem, it is for the best that you are not together. You seem like a really nice person. I would definitely take this time for yourself to heal and prioritize what is that you would like out of life. He will heal when he’s ready to heal.
