Please read codependent no more. Please don't pressure him for his "love" because very likely if he gets out of his program you will go back to where you were before he went into treatment. Let the process work for his best recovery. He WILL change if he hangs in there, and you have to give him time, have patience, and work your own issues out through Al-anon, CODA groups (if you can find them) mental health services have all kinds of booklets, even libraries where you can check out more information. Your Al-anon is a good resource for additional support. It's a long journey to get healthy but oh so worth it. You'll understand boundaries more, what a healthy relationship looks like without using, abuse, back and forth yo yo which really ultimately is EXHAUSTING for all!! Sending you hugs and best wishes for you!
