Lover? I don't know. I don't know if she loves me. I don't know if I love her. All I can say is, she's the one I think about. All the time. She's the voice I want to hear. She's the face I hope to see.
Honour a date, celebrate a milestone and wait not a moment longer to make someone, even just one, feel loved and appreciated.
Appreciation can make a day, even change a life. Your willingness to put it into words is all that is necessary.
