My boyfriend is now a famous model and I'm insecure..

Not so much that he'll leave me as much as he'll stop thinking I'm the most beautiful girl in the world. He's surrounded by such beautiful women at all times and it kills me inside. I know he finds them attractive (who wouldn't?), but I'm so afraid he won't find me that attractive anymore, that ill just descend to being an average woman. Where I know I have an edge over the other girls is my personality. But I also want him to desire me.. Ate personality and looks mutually exclusive?
