If I were to answer that question, I may say because she has tantalizing eyes, pretty, loves her family very much, loves God, hardworking, ..., and lots lots more, but I won't.
Yes all are good qualities... but for me those things are still limited in why I love her. I mean, all I'm saying is I love her for all she is which in truth cannot really be described by any other word.
I love you because I love you...
