Not sure what to say

Someone went to my friend and told her, "before my brother married so-and-so, he had a crush on you." Considering my friend is much younger than the guy mentioned, she thinks that he might have mistaken her for me. This is possible because we are just a year apart. And there were times that I did wonder. Now I just wonder if it was true. Did I miss a chance? Did I ever have a chance? Maybe I'm just wondering over nothing.
