I just started college to study for university as I workout a lot I get a lot of weird looks. However In one of my biology classes on a Tuesday there's this hot girl. s she's not actually part of my proper class and just study's biology as part of her specialism I only see her in biology and I added her on Facebook without ever speaking g to her first. So she didn't accept me then wen she saw me around she kept looking at me and then in class she kept looking at me up n down so at break I introduced myself to her and her friends. and she was a little shy but then started to be more talkative n not so quiet. I only find her attractive but I don't know if I should dig deeper because I don't want to seem a douche bag. What should I do?
