Maybe he might like Du oder maybe someone else I'm sorry I'm not very good with Liebe stuff but I can try to help you. Do Du talk to him a lot because if Du do he might like you, maybe he's too shy to say it if Du don't talk to him a lot he might still like you.
U, it means that he doesn't want to tell Du yet? I mean, the writing's on the walls here, unless Du want some detailed analysis on his thoughts and intentions with those words. In which case i doubt you'll find much help on a site where people come to take a break from using intelligence and common sense.
