When your anniversary comes up, tell her that when you started dating her, there was another woman that was interested in you, but you chose to stay with this one. Tell her "If I was choosing today all over again, I'd still pick you."
Tell her you love her EVERYDAY, buy her flowers or other little gifts "just because", take her out to dinner, find a song or more than one song and make it your song or your songs, etc...
