<human>: I don't want to be blatant and just be like "let me ask you something. Why are you so uninterested in me?" Basically, I (16M) started talking to this girl as soon as she came back to my high school (about a week ago.). Since then, I have gotten her number, and have been texting her for about 2 days, along with talking to her at school. She showed me her homecoming dress, and acted a little sad that she didn't have a date, so I decided I'd ask her. She said no, because she already said no to someone else (confirmed, I am friends with the guy) and that it wouldn't be very nice. Anyway, I slowly made it apparent that I am certainly interested in her. She doesn't do one word replies, not even close, but she does use "lol" a lot and tends to try to reply to things in a way that would just end the conversation. I want to know how to ask her why she seems so uninterested, without being cringey or weird about it. However, im terrible at thinking of this kind of stuff.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: how do I tell a girl she seems really uninterested with me, without sounding like a big fukboi?
