You think she likes me? (girls help me out)?

I just got home from a party at this park/football field. It was at night a little spooky. The girl I like would sometimes try to join in on conversations I was in and I would catch her staring at me when I wasn't talking. Then we found a car with a dirty blanket in the back and a skirt with a red stain on it in the front. (Turned out to be a biker's car not a rapist) we all checked it out and the girl I like starting clinging to my shirt. You think she likes me or no? I know like 2 or 3 other guys who like her and we're about to graduate so I want to know if I should give it a shot.
