This is true. Sometimes though the people who leave your life do so because of your own actions, and it's better for them to be without you than to keep you in their life.
the right one and the wrong ones also will leave you, Nothing will remain forever. its an illusion that the right ones will stay.
Sometimes people put up walls, not to keep others out, but to see who cares enough to break them down.
it's true that they come and go but they leave a lot of cracks and hurts ,broken hearts, eyes full of tears because we ve trusted them and thaught they are the true ones.
