<human>: Can you provide a brief overview of the text?

Okay, I have a sister who plays college softball. Back in March/April, I went to several of her games. Since I have been at these games, I have noticed one of my sisters teammates "checking me out" at least once, then as games were going on, she would hang out of the dugout and look in my eyes ( I was wearing sunglasses, so I don't know if it counts). And smile really big multiple times per game . 

 I don't know what any of this means. I have never spoken to her, not even like a "hey" or "what's up". I do have a pretty massive crush on this girl , and it just kinda seems like it is too good to be true. She did this every time I went to one of my sisters softball games (like 5 times) She also has asked my sister about me like who I am, what my name is, whatever that may mean . I haven't seen her since April though. But it was probably for the best (I had some things I wanted to take care of before I started pursuing girls.) What should I do? Should I talk to her or just let it die. I have made a positive improvement in my life, since the last time I saw her.
<bot>: I really like this girl, and she may reciprocate these feelings.But I'm not experienced in talking to girls, and I may have waited too long, What do I do?
