He likes something about you. And WHY would you be concerned with whether he likes you or not? Sorry, but are you THAT dim witted to not care? He is touching you inappropriately... which needs to stop.
He doesn't like you in a good way if he's being inappropriate. If you are not discouraging him from being inappropriate, he's probably gonna continue to do so and have absolutely no respect for you. Doesn't matter whether or not he "likes" you. Respect should always come first.
If he's touching you inappropriately, and you're letting him continue to do so while wondering if he likes you, it brings my attention to the fact that you might possibly get raped. As I mentioned in my comment on Kenneth1965's answer, he could already be wondering what else he can do to you and get away with. If it bothers you that he's touching you like that why not focus on getting him to stop? Hmm?
Yes he likes you, but he likes you in a wrong way. If he touches you inappropriate its because he's a perve! do not let anyone touch you in away that makes you feel uncomfortable! And if he continues to touch you like that, please report it to an adult that you trust. A boy who truly likes you will respect you :)
