Ilike this guy but i don't think he likes me back. he also goes to school somewhere else, but we see eachother every friday. he doesn't talk to me he just looks at me and looks away. what do i do..

You should try to strt a conversation with him or say hi introduce yourself or ask him how hes doing just talk to him i guess

Try to engage in a conversation with him but don't be creepy at the same time ya know? If he seems like he doesn't want to talk to you, walk away and watch netflix and eat ice cream. A man that doesn't care about you doesn't deserve you. 

The answer is true for your question.
