Welcome to SR - wander around, read, and share. It has done wonders for me. I also go to alanon now too. Here and at alanon are the only places I feel like I am not alone (there are no naranon in my area).
As Amy said, there is no cure for addiction. Recovery is a process that must be worked through. That goes for your BF who has to want to do it. But it also applies to YOU as well - not you working on his recovery, but you learning about yourself and your needs.
Now that you're here, I hope you can start to do things for yourself to help you on this journey. It is then that you can work towards healthy relationships.
