<human>: Some background information. This girl and I just met during a school trip and we got to know each other pretty well. I even asked her to prom, which she said yes. But after prom and AP exams, we kind of stopped talking (it's hard to find her at school since she's so involved in a lot of extra-curricular activities). 

I really liked her, but I just found out a few days ago that she liked someone else. But she wasn't actively looking for a relationship with him. Honestly, the moment I heard that, my heart sank and I felt pretty depressed. My friends tell me that she "liking" someone doesn't mean anything unless they start dating, so I still have a chance. 

But I'm pretty pessimistic and I feel like that if she likes someone else, I already lost half the battle. And historically, whenever I work hard to get something, I always fail. Every single time. 

I should also consider the fact that I'm a senior and she's a junior. But we're both not going anywhere during summer break, so I technically still have 2 months with her.

So should I let her go or go for her? I'm so conflicted...

Provide a brief overview of the text.
<bot>: The girl I like likes someone else, but she isn't looking for a active relationship with that person. Friends encourage me to pursue. Should I?
