Sometimes you become really fond of a person and even grow to love them but mostly due to the fact that they filled a hole in your life at a time where there was something missing. The situation and timing made them mean exponentially more to you than they normally would have. So, if both of you ever part ways and you think you always cared more for them than vice versa, just remember that their personal situation and time were different than yours, and that you may not have played the same role in their life that they played in yours.
