My crush sending confusing signals

Ok so my crush is confusing me. One second she is being an ass then the next she's giving me an extra pair of ray-cons. She also says she is dating 2 other people so I figured 'ah she's dating someone, I got no chance' then she does something extremely nice for me (no one else to my knowledge is getting this treatment from her)

She is a senior and I'm a junior (16 and 17)
