Love is a two way street ( giving and receiving). When you ignore the person that loves you, you stop giving love to that person. Usually you start to ignore the person that loves you due to other obligations such as a deadline coming up at work, a trip with friends, needy kids etc. Things on your to do list. These things are huge when you look at it in terms of hours or weeks but are small and can be insignificant when you compare it to relationship that you have with the person who loves you which could last 50 years or more. So the small things are the stars and the person who you love is the moon.
If you continue to ignore the person who you love by constantly prioritizing other things or people over them, they will get tired and leave you physically or emotionally. By the time you realize this, they person would be long gone.
How significant is the moon in relations to earth? very significant, the moon causes the tides in the oceans. Keep the moon priority number one.
