Does he like me or not

So there’s is this guy I do karate with and yesterday we all had lunch and there were a couple of kids there that I’m close to and I was playing with them and everytime I turned around he was there looking and smiling. we get along really well is flirty and we have almost done stuff with eachother but idk if he likes me or not he makes me laugh and I can’t stop smiling when I’m around him and when he is there I feel safe I don’t want to open up and unless I know for sure
