When the familiar starts to sound unfamiliar and the same words don't have the same meanings because they don't come from the same mouth, you know it's gone. When you start to hate the sound of something you once loved to hear only because it doesn't feel the same and because it isn't the right sound, you know it's gone. When soft sounds to you feel like sharp words and pointy edges that hurt rather than feel good because they remind you of something that could have been instead of something that could be, that's when you know it's gone; love is gone.
