I genuinely do believe that beauty (attractiveness) is in the eye of the beholder.
My husband finds me attractive no matter what because he loves, and therefore 'sees' the real me. I have been very ill in ways that have been detrimental to my physical appearance, I have a skin condition that sometimes looks pretty ugly, I have been overweight (and even underweight!!), I've had spotty skin and greasy hair and yet........my Wonderful Man has always looked at me through his rose coloured spectacles and thought of me as beautiful. And that's how I feel about him too, although it's not hard as apart from his hair changing from carrotty red to white he looks pretty much the same as when we got married. 
(One of my female students met him for the first time last week and commented to his face that he is "a very pretty man, so, so pretty"!
