Guy says i have beautiful lips? what do i do?

So I just started a new school. I'm in the eighth grade you see, and at our school seventh and eighth graders are in the same building as the highschoolers. Well there are two sections, but almost all the highschoolers have cles in the middle school part, and all the middle schoolers cles in the highschool. I go to the highschool for french everyday. Well this guy asked me to be my friend on facebook. I didn't know him but I added him which I usually don't due, but I gave it an exeption due to curiousity. He comented on my profile pic sayin "damn you're beautiful". I thought what the hell at first and on chat i asked him if I even knew him and he said no but i see you at school. Like that wasn't unusual cuz, not to be snobish or anything, a lot of guys in the school think I'm beautiful or hott or pretty. But like "beautiful" usually signifyes they don't want strait in your pants. Turns out he's in 11th grade. He's really nice and we have a lot of the same interists. He asked me to hang with him on early release and was fine when I said I couldn't. He hasn't been pushy at all. I really like him so far, though I haven't really met him in person. He used to be a druggy but he said he was wrong and that he'll never do that again. he saiid he was being unhealthy. Cuz he's been through a hard child hood like me, and he addmitted to greiving in the wrong way. He seems to be very genuinly sensere, sensative, and real... and he really likes me. We have been talking for two weeks on facebook, cuz we are both pretty much always on. And I really have a good feeling about him. Like he really wants to get to know me. But he just sent me a message onn fb sayin "there's somethiin I've wanted to tell you sense I first saw you" I said "now what is that" and he says "you have the most beautiful lips I have ever seen" and then somethin about wanting to kiss me. What do I say to that? I really like him, but I don't know if I'm ready to kiss him. I've never kissed anyone before
