Why does he leave so quick

Princess

So whenever I see him and his freinds he doesn’t stop staring at me he smiles at me and when I compliment him he giggles but when I’m there he always try’s to find an excuse to leave as quickly as possible I don’t understand why why would he does this I chill with his male freinds all the time he gave me a cuddle when he left I don’t understand why he always has a reason to wanna leave
