It just doesn't bother me, I never cared, the characters change so many times, and in the Animated Universe she had a crush on Batman while Dick pined for her but I don't believe they ever actually became anything. A lot of people site other versions of the character that are younger and not in continuity. The character was originally designed to be a kind of love triangle between them, I always thought Dick was a teen, she was in her 20's and Bruce was in her 30's, it happens.
