I'm so glad you found this forum. I read your post and it mirrors my own life. Read the book Codependent no more my Melody Beattie. I too was his best friend. Live in "hole". He is dead now and detaching is the best thing I could've done when after the rehab stunt, he relapsed into hyperusing. We are here for you on this forum. So many similiar stories. The all end in betrayal, lies, theft, deciet. Pain. Implement your self preservation. IT's a must and this forum is a God send!
