Why does he bother me so much?

So I met this guy this semester through a friend. I had only seen him around before and one day he added me on Facebook. I was one of his first Facebook friends too. I never even knew he knew my name. Well we started talking and he would text me good morning and stuff like that. He used to also call me pretty. One day his friend wasn't at school and he texted me he was with us for lunch and ever since he's always say with me and my friends. Now he barely ever texts me at all and sometimes never replies. Every time I asked him what he thought about me he avoided the question. Since he sits with my friends and I he knew I was talking to another guy and that I find others cute. He also told me how he thinks I like everyone. I used to not really care about him but now it's bothering me how he acts. When we sit together at lunch he ALWAYS bothers me like he calls me smurf because my hair is blue and I'm way shorter than him and he's always telling me I'm like a baby and so little. He also always hits me and plays with my hands. He's always making jokes about me or bothering me for something. Today he mixed my water with his water that he already took sips from. he saw that I was really mad and I said I was going to leave so I took my tray and was about to go when he took it from me and threw it away himself. I don't know why I suddenly care that he acts like that. Why do you guys think?

Also, he's a Jehovah's Witness so he's not allowed to hang out with anyone outside his religion or date anyone. I don't know if that's relevant to this.
