“I love you to the moon and back is a nice thing to say as it means you love someone a hell of a lot but it is not enough to express what I feel for you. The moon is actually visible and the distance to the moon and back is caculatable so in a way limited. So what about I love you to beyond the universe and back instead. It just comes closer to what I feel for you than "to the moon and back".”
