Rejected a girl to hang out

[Tylermax]

So I've made a couple of posts about this girl already. She's the one from uni who didn't reply to my message and approached me after a week to tell me in person she isn't interested and keeps talking to me though. I've figured out that talking to her is inevitable cuz we are in the same class but she's always the one who initiates it. It doesn't feel like she tryana friendzone she's just seeking attention/someone who she feels familiar with talking to in the breaks or during classes etc. So an hour ago while I was sitting and we had break she approached me I said "hey what's up " and she was like " let's go outside " and I told her "naah I'll stay here" and I was expecting this happening. I visioned this interaction I already knew she would come to me as if I am some type of a beta male following her and chilling with her as if we are somehow friends after she rejected me erotically. And the funny thing is she didn't leave she stayed in the same position talking to the girl who is sitting next to me. I mean wtf she wants from me??? Tell me.
