The moral of the song in my opinion is to Never Give Up, you may face hard times in your life whether it's with someone you care for or not, but ultimately don't give up on anything you love. In this song Aaron is waiting for someone important to him and they are doing the same for him. They have been through too much to just give up and there is a part of them that won't allow them to give up. They will always be waiting, trying to make things work when their relationship goes through a hard time.
