Boy problems

Okay so I really like this guy and don't know what to do. We've never spoken in school or anything but he'll text me. Usually I have to text him first. And when I sent nudes to him he replied saying 'k thanks' ...I thought he was disinterested but then he said he wanted to go on a date. It was awkward but I loved every moment of it. Then a week after I saw him with his mates out, and I said hi and he said hi too. Then I replied saying how are you and none of them responded..they heard me and just walked away. like idk I just feel weird about him. I can't tell if he wants me or not. What do I do?
