We never really attached to each other. Once we get used to it, a new normal has come. That's why, when we choose a different path, it will break us, but never really kill us. And even when the loved one is gone from this world, we will eventually get used to live without her/him/them.

In the end, we should love ourselves more than any other creatures in the world. We live not only for one people. And even if it's true, we should live for ourselves.
