Boy problems

This boy and I have been talking for a very long time and I have really started to like him but he never really talks to me when we see eachother in person. Just smiles and waves and winks.He also told some of my friends at a party he was into me. L He rarely replys to me over text but I've been told he's pretty disconnected from his phone..... 
I'm wondering if I should ask if he is over it so I can move on or just stick with it.
