My Friend (18f) wants me (17m) to ask her to Prom. Is this crushy behavior?

Hi, looking for some input on my situation and I was wondering if I could get some feedback from others, especially girls. Do girls view prom as a date? I (17m) am currently a senior in high school and prom is in about a month. Last week, my sister (14f) told me that a girl in her grade told her that my friend Emily (fake name lol) (18f) wants me to ask her to prom. This kind of came out of nowhere to me.

Emily and this other girl are both on the varsity soccer team and apparently they were all talking about prom. Now Emily is my friend who I have known for six years. We are not bff's or anything and I only occasionally see her outside of school and school events so we know each other well but are not super close. She would always want to dance with me for one or two songs at dances in the past, but for her to apparently put it out there that she wants me to ask her to prom, I would just like to know how to read the situation. Obviously it could just be that she wants to go as friends as neither of us are in relationships and she would feel comfortable with me as her date in which case I would think she could just talk to me about in person, but it also could be that she wants more and I have been kind of thinking about it all day. I used to have feelings for her, but "put them away" myself a few years ago as I didn't think they were reciprocated so have just been viewing our relationship as two platonic friends.

The other thing is I have been crushing a bit on a different girl, but the sudden realization that maybe Emily possibly has feelings has kind of flipped things on its head and has me in my feelings a bit. Does this seem like the behavior of someone harboring a crush? I plan on talking to Emily tomorrow when I see her, but if anyone has been in a similar situation or could give me any pointers I'd appreciate it.
