It's great that you want to be supportive to your BF. There are quite a few of us here doing this w/o the support of someone. So you educating yourself and asking question to help him is terriffic. Just know, beyond that, there's not much you can do to aid in his recovery. He will if HE wants to. If he's not ready yet, then it's very possible you will go through another "cycle" of using, not using, using......
Because addiction is a family issue, you'll need to strengthen yourself emotionally in the event your faced tougher decisions about your BF, relationship. He is the only one who can make himself stop. But having a loving, interested person along side goes a long way to aid in recovery.
Be sure to take care of you as well.
All the best.
rue, that was well put.
Xanax in that quantity is very dangerous. I do hope he is not drinking too. It can be deadly. Keep supporting him as best as you can. It is up to him to change. Sometimes if you can get him on here. It can help.
Show him this forum and your post. If he truly want's to stay clean this may be the wakeup call for him. Truly knowing how you feel might also turn on that light.
