Relationship help... a guy likes a girl...?

Just tell this girl how you feel, you seem like a really sweet guy, not trying to hook up with her instantly. Your taking things slow even if you two are not "dating" yet, and she appreciated that. So if you get it off your chest then everything's easier, even if she doesn't return feelings. And even if you can have a romantic relationship, you said you can't risk losing her, so stay by her side as a friend always if things don't work out.
