Girl's Advice: What should I do?

There is a girl that I really like in my gym class. We went to the same middle school so we know each other. Last Thursday when we were playing baseball, she purposely kept missing the ball and she smiled at me. But the way she smiled at me wasn't the friend type smile. Eventually, she hit the ball and scored a run. After, she sat next to me on the grass since we were playing on the grass and we talked for a little bit. By the way, this is not the first time. This is the second time she has walked up to me and talked to me. I don't think she just wants to be friends because I have known her for almost a year and she never once tried talking to me before these two times. After waiting three days for her to talk to me again, she didn't. So yesterday I decided to talk to her but the conversation didn't last long since her friend started talking to her as well. But when I talked to her she seemed pretty enthusiastic and didn't sound uninterested. But today, I was going to talk to her again but she was always with her friends and I didn't talk to her. We only said hi to each other. I only have 2 days left with her. I really like her but i don't know if she likes me the same way. What should I do?Girl's Advice: What should I do?
find a time where you can be alone and just talk and then just tell her that you like her and ask her if she likes you. i always smile when i guy says ';you know i always did like you'; but only after we have known each other and are sort of friends. so maybe she will too.
