Used to be a Casanova? No no... he was just tired of searching for his true love. And now that he has found it, he's not willing to let it go. It's like if he's not with her then he doesn't know what to do. He's so happy right now that he'd go home early and only remember his love or their kisses. He's not afraid that if he goes out he will meet up with somebody else. No. He only WANTS to think about her, so no PETTY distractions!
