Why does he acts like this? is he just shy or doesn't like me?

there is this guy I know through a mutual friend. My friend told him that I think he is cute and that I want to be his friend. When we met, a lot of his classmates were there and we didn't talk because we were both shy. I texted him to apologize for not talking and he seemed nice. The only question he asked me was how I knew our mutual friend. After that he stopped texting me. I started to lose interest, but one day he said hi to me at school. I nodded at him. Afterwards I was happy with his gesture and looked in his direction and smiled and he was already looking at me, he seemed shy and smiled and "hid" next to a friend. Then at the bus stop he made a face and walked away. He told my friend that he didn't know if it was me. Now he says hi to me at school, but he doesn't text me. My friend says he's really shy, especially with people outside of his class, and that he's never had any experience with girls and he doesn't text me because he doesn't know what to say. i texted the guy that I wanted to get to know him but I never know what to say, and he said that's normal and that it will get better. I suggested that we find a way to get to know each other better and he said "let's start by saying hello at school first๐Ÿ˜‚". Then I said that if he doesn't want to he can tell me and he said that he doesn't mind a new friendship. Did he say friendship because our mutual friend told him that I wanted to be his "friend"? Or is he too shy and wants to be cautious since he has no experience? Or is he just not interested? I asked him if he wanted to date, and after eight hours he read the message and replied "oh my god, when?" and "with who?" I said "me", then he told me "just the 2 of us?", so I wrote yes and he wrote "omg that would be a little cringe, we don't even know each other". and I told he's right but I always hang out with someone to know each other. and he said he thinks it's better to talk in school and know each other better. what do u think? thanks ๐Ÿ’—๐Ÿซถ
