Love yourself and you'll become your own best friend. Appreciate the qualities he loves in you. He's with you for a reason: your sweet nature, your beautiful eyes, your warmth, charm, sex appeal...oh yes!
There's always going to be someone with bigger jugs or a more picture-perfect smile than yours, but that doesn't take anything away from your qualities. Nobody's perfect, and that bimbo he might eye up in the lift doesn't have your sense of humour or lovely skin!
It's only natural to check out the opposite sex - we do it too, but it doesn't amount to anything and it doesn't mean we're about to hop into bed with any hot stranger we might eye up in the street.
