The way I see it.

Nothing lasts forever. Change is inevitable. This is why you’ve never seen me claim an one and only “B.F.F.”

There are things that you choose to share with people. And there are things you choose to share with no one. If you choose not to share certain things with anyone, then that’s totally up to you. If you decide to tell someone everything, then that is completely up to you. But you can’t be mad at someone who doesn’t want to tell all of their business to you, because it’s their business. Even if you’ve told them all of your “business”. It’s expected in return, not guaranteed.  

Don’t take it personal and think that the person just didn’t want to share it with you, when they haven’t shared it with anyone else.
