I am the complete opposite of his ex?

My new boyfriend recently (very recently) got out of a serious relationship which worries me. He was dumped by her. I have been told I am out of his league, or that I'm prettier than his ex but I can't help but worry he may be using me to get back at her. I am the complete opposite of her. I've met her before and she was super bubbly, ditzy, and overly sweet. I on the other hand am intelligent, slightly socially awkward, and on the quieter side. Do you think this is a sign I am just a rebound? He never mentions his ex, and I'm almost positive they don't speak anymore but I can't help but wonder. What do you think this means?
