My whole classroom was looking at books at the library, when this girl took a step closer by my side, so I took a step to be polite, then she took another step closer and rubbed my arm before I walked away trying to be polite and feeling uncomfortable. the next day I bought her twice glancing over at me. I seriously think she has a crush on me. Any advice?

I also like her.

I am pretty shy with these thigs, I don't know much about her either, and I don't want to approach her until I know for sure.

no, what she did was just touch me with her upper arm onto my upper arm an she stayed there until I left and then she leaned a little bit. I was kind of freaking out. I couldn't quite recall very well when I posted this thread

thanks everybody

one more thing... the past school year she didn't like me, or at least I didn't know. this behavior was kinda sus tho
