Hi Chloe,
Welcome to SR. I'm so glad you found this sight. I know how it feels to feel so alone in this. And boy do I understand the anger thing, too. Just know you're not alone anymore. There are so many good people here who are going through the same thing you are.
I did the detective thing for a while until I realized it is humanly impossible to police someone 24/7. I started attending Al Anon meetings where they taught me I am not my AD's keeper, that she is an adult and it's up to her to decide if she wants recovery. No matter how hard I tried to keep a watch on her, or guilt her, or talk to her, or cry, or beg, she just wasn't going to seek recovery until she was ready.
I also learned the 3 C's:
I didn't CAUSE the addiction
I can't CURE the addiction
I can't CONTROL the addiction
Please stick around. If you can't make face to face meeting, please keep reading on here. This place was a lifesaver for me in my early recovery!
Hugs to you and I hope to see you around some more.
Hangin' In
