Treat her good
Love her like she's the only girl in the world besides your mom. Bring her up when she's feeling down. Try to make her smile when she's not in the mood, listen to her when she has problems and has no one to talk too. Make her laugh, make her love you more each day, make her angry then kiss her unexpectedly but what ever you do don't make her cry, don't make her feel worthless to you... Cause she was a queen before she met you and she will still remain a queen after you are no longer in her life.
