Significant other with addiction

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.

Hi yossarian87. Welcome to Psych Central. Sorry for your loss which probably occurred back when your gf started on drugs again. They are sick and unable to control themselves. It is not your fault. You did nothing wrong. It is difficult dealing with people who are addicts or who are untreated for mental illness and self medicating. It is not your fault. But you may have to give up on some hopes that partners cling to about helping the partner suffering from addiction to get "clean". That is up to the partner. There is nothing we can do to change them. And when they leave, we can't bring them back. Maybe she will get help, but putting your life on hold may not be a good strategy.

It sounds like you could benefit from therapy to help you sort things out. There is a lot to sort out trying to be an advocate and or partner for someone that is challenged by their life. You can also send to a question to a volunteer therapist here at Psych Central https://psychcentral.com/ask-the-therapist/

Sorry to hear about your experience, you did nothing wrong,assuming you didn't use anything in front of her yourself. Which I am presuming not.
I would suggest looking at support groups for SO's of addicts. Just so you can see others experiences.
You are not alone, this is a common story.
Relapse can happen for many reasons, most commonly,untreated mental health issues. Falling back into the wrong social circle. Most common amongst younger users is they just haven't fallen hard enough or far enough to genuinely want to give it up. Especially if they have family or friends who keep picking them up so they don't hit rock bottom.
You did nothing wrong, she just isn't ready to give up that life.
Look into protecting yourself should she return looking for help. Which probably means money, and be prepared for unpleasantness if you refuse.
Take the previous posters advice and take sometime with a professional to get things straight in your head.

I am an addict, I have been for 24 years. You cannot help her. She has to want it, more than anything else.

Good luck, take care of yourself.

I'm kind of going through something similar, except we haven't even gotten to the status of gf bf. There are times where I think he doesn't like me anymore, he doesn't really say hi or talk to me, other times he talks and seems interested, we talked about going on a date but I don't think it will actually happen... he gives me little gifts, other times he will walk right past me. I don't know what I've done....he will bring women to his place and use...is it sexual too? He's told me he hasn't been with a women in years...I am starting to take this personally and I'm upset. Do you just let them go? Can loving them make them sicker? How can you show them love and the feeling of someone being there? I write him letters with just loving feelings....he's sad and depressed....I don't know if I could to a shoulder to him....

I completely understand what you are going through..
