For context, there’s this girl I like, I’m also a girl, I have a crush on her, she knows I like her but we aren’t really close, we just know each others names. Now, This all just recently happened. My crush texted me for no reason at all, she knows I like her and had no reason to text me, she also followed me on Instagram at 3am. Now my bff invited her to hang out at the carnival with us and one other friend of mine for my birthday, and she said yes. I also always feel like a catch her staring at me. Is it possible I have a chance with her?

Anything is possible, but can I ask your ages? Obviously you are excited about the possibilities, because you like her, and that's NORMAL, but you will just have to wait and see what happens next. Enjoy your birthday with your BFF and new friend.

We are teenagers. 15.

She could like you as well or maybe she wants to get to know you better
Don't read anything into it, just have fun and see where it goes
