My girlfriend is somewhat innocent, and I feel a strong sense of protectiveness towards her.

Hi everyone, I’m a 25-year-old guy, and my girlfriend, who’s 24, means the world to me. She truly is the girl of my dreams in every way. That said, she’s quite trusting and somewhat innocent, while I have a good grasp of how the world works and I'm not afraid to take action when necessary. We live in India, which can be a challenging environment in terms of safety. Recently, she moved to a new city for her job and mentioned that some friends were planning a sleepover at her place. I was having a good time playing video games when I received a text from her saying, “The girls are going out, and I’ll join them. X and I will definitely go, even if the others might not.” While I know she’s at a responsible age, I’m concerned about the idea of her going out at 2 a.m. with just a couple of friends. How can I express my concerns without coming across as controlling or overly authoritative?
