Is she just really friendly??! 10 points?

[Hunter]

I've known her since 10th. We're in 12th & have a class together. We don't text anymore but we do like each-others stuff on social media & she pokes me on FB. I asked her out in 10th and she rejected me, but now we talk fine.

She sat close to me in gym one time and kept tapping my thigh and leg by accident., She didn't apologize at all. She makes eye contact with me a lot & says hi to me in the hallways and smiles. She always stares at me while talking and I never stare at her boobs or anything. She gives me high fives/ touches my arm in the hallway.

Today, she sat in front of me & when she was stretching, she looked back at me and smile and then said 'That felt good, I'm stressed.' She asked me (yelling playfully) How I was and I replied and asked her the same. She rubbed my shoulders once & she was talking about our friend on how she talks to me more b.c he gets on her nerves sometimes by having a chip on his shoulder. She doesn't seem to like me but she flirts a lot. She has a bf, but their relationship is rocky.
why would she want me to ask her out now? but not when we were in 10th grade>
