If you do have strong feelings for him then you know it's possible, right? Whether or not it's appropriate is for you to decide. I suggest you try to make your decisions based on reason and logic rather than feelings. I know that can be difficult but it's the best thing to do.
Maybe you don't like him, but the idea of him. Maybe you just like the possibility of someone liking you so your mind goes to all sorts of places. Do you know much about him? Do you guys talk a lot? All things to consider.
