Why did he give me his number if he doesn't talk to me?

I worked with a guy in groups for my French class. We had small talk and later he asked me for my Facebook. I told him I don't have one. I was going to give him my number but he wrote his number in a paper. I have always been the first to text him. When I text him, he limits himself to say hi. He responds to my messages an hour later. In class, he comes to class late and leaves early. I can't talk to him before or after class. When we have to work in partners, it seems like he doesn't want to work with me. He's really quiet. Why did he ask for my Facebook? Why did he even give me his number?
