It's not that your boyfriend doesn't love you, but rather that the addiction is more powerful than anything in the world to him--even you. He first and foremost must want to quit for himself. Any other reason wont hold up. His getting help now is a good sign, but you must realize that you can't do this for him or wish it away. It will be very hard work on his part. Start working on yourself. Learn all you can about addiction and how we loved ones play in to the addiction. If you intend to stay with your boyfriend, after his detox and recovery, you must learn what an enabler is and stay as far away from enabling as you can. Enabling only makes the problem worse. Trust me--we've been there and done that and it doesn't work.
