A tiger doesn't change his stripes. I know you like him, he's been attentive, but IMO, keep him as only a friend. I can't believe I'd ever be saying this, having once been your age, a gazillion years ago...but looking back, I realized what I didn't really know about people (mainly guys) at the time. You have your whole life ahead of you. You'll meet so many guys, I'm sure. And get your heart broken too. But that's how it is. A good learning experience. You'll know when the right guy shows up. Chin up kiddo!
