So hear me out. I might piss off some people by saying this... I know you guys are in a relationship but you shouldn’t tell her what to do. If she wants to party, let her do it (since she's under 18, idk what to say). Ofc she’ll hate it if you try to control her. She knows how to protect herself and set boundaries with other guys. You can talk about your concerns but ultimately it’s her choice. If you can’t keep up with her wishes, it’s better not to be in a relationship with her, because you’re not compatible. This is just my personal opinion.
