I'm pissed at my girlfriends drinking habits when I'm also drinking
Why are you mad when you are drinking too?
I just don't like her drinking like I do.
You should be more understanding if you are doing the same thing. If you are concerned about it you should both get help but don't just single her out.
I can't fix this shit alone. I just want to get her help and make sure she's not doing it too much. She can't be like me.
It's wonderful you want her to get healthy, but it may be really hard for her to try when you are tempting her with your own drinking. How about you two try going to rehab together?
