Do you think shes just tryin to be a good friend or more?

so on wensday me and this girl always hang out in our cl and we eat lumch together. like the cl before the cl we have i ped by her. and she looked at me and didnt say anything, and i ment to say something but i didnt (bad part on my side) :/ so we were walkin to lunch together and i saw one of my friends, he pushed me earlier that day so i told him to never do it again. and right after i said that she pushed me. and then when we were walking in the hall on the way back she asked what i would do if she slapped me. i took her arms and shook her (in a flirting/joking way) and so then i took her backpack and started walking around with it on and she was laughin so hard b.c it was soo small. but today in lunch/ cl she seemed a little quieter than normal, i mean i have 5 packs of gum and she asked for a pack and i threw her an empty1 and she threw it at me so then i gave her a piece and i took my rapper and threw it at her. she threw a peice of paper crumbled up at me. but at lunch she didnt talk to me as much as she did, and also when she is alone she is really shy to talk to me. and like today i saw her on fb. (i rarely ever) so like i started to talk but she would sometimes answer quick and then slow or w.e i let her take her time a stuff. so i asked a couple questions like whats up and stuff. i got like short answers, like nm wbu or stuff, and so i asjed how her sport was and she accually started to talk. but after like 10 min talkin bout her sport she quickly said but i gtg. and i said alright kool yoi wanna txt me? ( i dont have her number) idk i was tryin to find a way to get jher #. but idk if facebook has a delayed time when they get off or what but she never answered and she got off 5 min after i asked. so does she like want to be friends or does she like me?
