Does she like me or not?

We've known each other for a good 4 years, but this year we have been talking/ hanging out a lot more. He both have a joking matter so we'll both make fun of someone or people sometimes each other. But she will sometimes like air hit me (like she was making fun of these people for touching each other she looked at me and said ahhh waving her hands at like pretending to hit me) or something because she sits across from me, We'll walk together in the hallway and talk at the end of school. I sorta like her, and we both make each other smile and laugh. We've hung out a couple times during the school year (sledding, my place, and skiing/super bowl party.) The other day I asked her if she was gonna go to after school chem help and she said she wasn't but decided to after I asked her. And today the teacher told us that there will be no more water fountain pes left and if you wanted water bring a water bottle and she grabbed her bottle and said ahh Yeah! and pretended to open her water and spray me with it, and I just smiled and laughed. Also I was asked by nearly 10 people saying "when you asking her to Prom?!" and I replied saying "I'm not going, because like her I'm sure she isn't interested in spending a ton of money or wanting to go, she only went because the foreign exchange kid asked her. I want to ask her though" And when I asked her how prom was she said it was super gay her date didn't pay her attention, Barely danced with her, and said that he was tired and didn't want to go to an after party, and I was thinking I should'a asked her to prom... Then she said that she Wanted to just punch him while swinging her arm playfully and laughing pretending to hit me. Thanks for hearing me rant on and on. If you say yes she does then what should I do? Thanks Ya'll.
