bees and the birds

do you think guys are generally not contented with their partners...? well, been there and i must say yes..last month me and my ex had dinner good thing we end up as friends after breaking up.we talked about our past relationships> one thing that made me amazed about him is his honesty. I dont know if i want to slap him or praise him, But he said maybe the reason why until now he's still unattached with somebody else is just because he's not contented...he's still craving for something until now he's searching,,,
