<human>: Can you provide a brief rundown of the text in within 3 sentences?

I am 17, but only for about another month. My friend turned 15 a few weeks ago. We've been friends all throughout this first semester. I think she has a crush on me. No issue right? But then we started texting and I made the stupid ass choice to flirt with her and lead her on. I think she's cute, but the age difference, almost 3 years, makes me a little uncomfortable. I'Ve never been in a relationship before and I feel like I would be taking advantage of her. She is somewhat mature, but I'm a senior with a semester left and she's a freshman. I want to be in a happy, stable relationship. Physicality is secondary. I don't know what to do. I don't want to hurt her. I don't want to be that guy that everyone thinks is taking advantage of an innocent girl.
<bot>: My freshman friend has a crush on me and I encouraged it And now regret it. 3 year Age difference has me feeling like a pedder ass.
