I usually become a ghost to those who no longer deserve my time. I've never seen a point in explaining my absence to someone who failed to appreciate my presence. You don't owe any explanations to those who hurt you.
Wide awake as your soul remains tired. Sitting silently under the moon as your mind continues to scream. you're losing yourself, you're losing sleep but he's losing you. some time soon, the thought of him will no longer keep you up at night.
The best feeling is being able to miss someone who actually makes an effort to make you feel good, feel peace.
