Don't force yourself to smile when your vision is all blurry and your eyes are wet and red. Don't push him to stay. Don't. Never. If he wants to let you go, let yourself go. If he's already tired, don't plead to make him stay. What will you do? Wait. Feel the pain. That's the thing about it, it really demands to be felt. It demands to make you feel like hell. It demands to make you suffer. What did you do to deserve this? There's only one reason. You chose to fell inlove. You chose to be happy but as what they say "there's always an opposite side of everything". He may be the reason of your happiness,but remember, Dear, He'll still make you sad. Cause that's it. That's love. You chose it. Deal with it.
