obsessed with this random girl?

okay so for context: i’m also a girl.

so i met this girl through my boyfriend, she’s one of his friends. i wouldn’t say they’re that super close or anything but in the same friendgroup. she’s the person that is the loudest one in the room, she’s actually pretty funny but in a chronically online way, and she strikes me as someone who has a lot of friends. we’ve been at a couple smaller parties together and we always chat, she’s really outgoing so it’s easy to talk to her esp when i didn’t really know my boyfriends friends that well at that point. ANYWAYS- i’m like weirdly obsessed with her? like i find myself always stalking her instagram or actually viewing her instagram stories and looking at the photo for what usually feels like too long. i have no idea why im so invested in her life we’ve hung out maybe like 5 times and she’s cool and i like her but idk??? am i being a freak?
