Signs Of Affection! Does He like Me Or Not?

Ok a few days ago I got over my crush and now i think he's starting to flirt with me! Are these signs if someone like u? 1.He stares at me 2. When cried (cause i got hurt badly) i was was sent to the office and when i came back my friend told me that he kept staring at the door. 3. When I play manhunt (don't judge-.-) he always gets me. Can anyone tel me if these are signs?
