How can I express myself to me?

How can I tell this guy how I feel without scaring him off? he's the really slick type...so I'm afraid that if what i say to him will be too loveydovey. So I'm wondering; in YOUR words, what would you say to him? For example, something I would say is, "I dig you a lot, and I want to be your girl because I know I'll treat you better than any other brat you have been with"......but then again it doesn't really sound so good to me. Does it to you? What would you say in your own words without sounding like a creeper. If you give me something to say, I wont just steal it, I'll get an idea out of it and make it into something my own. I'm just really blank right now and I second guess everything I want to say but think I cannot becaue I'm afraid of his reaction. I know for sure though, that he doesn't like a clingy girl with all that corny love...I just want to be straight up with him and blunt but cool at the same time.... Love is hard, esp when you have to express your feelings to someone that's very detached and cool. And I really like this guy. But I'm not sure IF he knows I want to become close to him.. and be his girl. But it's worth a try right? I know he likes me...but I feel that if I don't express myself sooner or later he'll get distanct. Thank you for your words in advance. All I wanna know is what YOU would say if YOU were in MY shoes right now.
