Should I break up with him?

My boyfriend (28M) mentioned that I (30F) am not the person he dreamed of as his partner. And I'm not sure if I should break up with him.<br><br>I have been with my boyfriend for 2 years, and 2 months ago, he mentioned that he had a dream when he was 18 which said that he was in a relationship with a completely different girl. His dream girl is the exact opposite of me in every way - she has curly hair, while I have straight hair; she is blonde, while I am brunette; she has blue eyes, while I have green eyes; she is tall, while I am a petite; she is outgoing, while I am introverted, etc. I felt pretty bummed that he knew exactly what his type is. I am scared that he will find the girl of his dreams and leave me for her. I don't know what to do now.
