I'm going to set limits or ultimatums to my gf with her drinking
Why do you want to set limits with your girlfriend's drinking?
She hasn't really done anything. I just want her to do what I tell her to do.
Telling your gf how and when she can drink is rude when her behavior is not harmful to anyone. You should let your gf make her own decisions about her level of drinking if she can clearly handle her alcohol.
Yeah... but... I just want her to quit, sleep at home and quit drinking. I shouldn't have to get up every night because she drunk too much.
It sounds like she isn't hurting anyone though, and these are all just slight annoyances. You should just let her have fun and maybe drink along with her!
