HELP!! WHY does he look away when we walk past each other now?

I think , he probably thinks you don't like him. He probably thinks you like him more as a friend or less than that. You don't really show interest in him , even though you really do , he can't see it. You might be shy but you can at least talk to him a bit more and maybe you'll start to notice your not so shy around him like before. I used to be like you , but I finally started talking a bit more and became less shy around him , and now we've been together for a year <3
