It's not out of the ordinary to look for someone who attracts you physically. I'm the same way. I notice looks, and that's why I give them a chance to show their personality. The sweetest person in the world would not attract me if they weren't good looking. Obviously a personality matters too, but its people's looks that initially draws you in, and it's their personality that either keeps you, or drives you away. As for Chloe.. that's kind of weird lol. She's a celeb and you will not ever be with her. It probably is a phase based on your age, but it is still unhealthy to compare people to someone you don't even know.
May the wind always be at your back and the sun upon your face. And may the winds of destiny carry you aloft to dance with the stars
