Please tell me she isn't a slut?

This girl I like has had a past I hear a numerous sides on. Her side is she thinks her past boyfriends were disgusting and creepy and even wen we all hung out they sealed distant, and she spent amplifier of the time talking with me. She broke up with her last BF because he spread rumors he was getting sum but she said he wasn't. She is also a religious girl who hangs with her family alot. The other sides of the story are from others makes her sound like a slut from all the rumors of guys not her BF getting some, so I know bast on her past dosent like them. These guys are also the jocks of the lesser sports teams and has brought me to a few fights getting me cut from our soccer team. From my experiences she is a shy girl who likes to have fun, dosent like parties but loves dances and never misses a chance to flirt with me. She has told me she had a crush on me all through high school and I have too. I want to ask her out but I don't want to date a slut. She has awards for being the most beautiful girl in band and having the hottest body in school. For thoughs reasons I'm uncertain about her.
