Is it normal to have such up and down feelings about a guy?

You dont think the guy is that attractive.. yet you want to do ual things with him. You've become super close as friends with him, but once and a while wonder if you're fooling yourself to think you feel more. That when you're with him theirs nowhere you'd rather be.. but when you're away from him, sometimes you forget that. That when you're talking to him you wish you could be there with him right then, but when you arent talking, you almost feel turned off by him. That when you're apart sometimes you'd do anything to be with him, you keep thinking about how amazing he is and how much you've fallen for him, but at other times doubt yourself and think that you're just not into him that way. Is this normal, how come when i'm with him i always want to hold his hand, but right now i'm scared if we see each other we'll snuggle and I'll lead him on nad hurt him. Why am I so back and forth when he deserves steady? Is it just happening fast, is taht why I have such back and forth tendencies? How can i feel so strongly one minute, love him to death, and in another minute, be scared of getting into a relationship with him b'cuz i feel like i dont feel that way? How can such extremes both be present, is it caused by something else? Do I like him but am just pushing him away for some reason? Or do i not like him romantically, but am fooling myself thinking i do? How come when i think i may not like him my heart fights me on it, but when i say i do my heart sometimes tells me i'm lying. I just dont get it, why am i feeling this way? What do i do?
