Unbeing Dead Isn't Being Alive.

 It's the worst feeling in the world when you slowly grow apart from someone who means the world to you. You can feel it happening, every single part of your consciousness is screaming "No, please, this can't be real.", but in the end, there's nothing you can do to stop this whole process. It's natural. People make new experiences, get to know new people and change.
Change is good. Change is necessary. But change leads to hearts being broken and best friends growing apart from each other, even if none of them ever saw this coming, let away wanted this to happen.
So you start to miss them, or rather the person they were when things were still beautiful and simple. You start to look at old pictures and wonder what went wrong and if you could have done something to save your relationship. No, you couldn't.
But then something changes. You start to talk to them again, maybe send them a text when something randomly reminds you of them. And then, in the blink of an eye, you're close again and it feels so indescribably good to finally have them back.
So eventually, growing apart is not as bad as you think. Sometimes you must first miss something to learn to appreciate it. And when you have it back, you will never want to let it go.
