My girlfriend has struggled with addiction to drugs. She recently completed a rehabilitation program and moved in with me shortly after that. When she was completely sober things were absolutely perfect. But a couple months ago she started smoking pot, then she started using other drugs. Tonight she moved out of the house to live with other drug users. She was cruel and refused to even look at me. What did I do wrong? I never abused her, I was always supportive, I put her first in everything.

What went wrong here? Has anyone ever experienced anything similar to this? Please, I just need to talk to someone.
