At first, their silence feels like betrayal. It leaves you heartbroken, it makes you question everything - whether what you had was real or not. Did their feelings disappear overnight or did they not have any from the beginning? You keep returning to your conversation, wishing they'd just write back, or call you, or give you some kind of response. Some kind of closure that would help you move on. First you despise them for discarding you so easily from their life, then you tell yourself, even if they return, you'd never let them back in, all the while hoping they do return to you. After a while though, you just see their silence for what it is. An answer to your questions. They didn't care enough to acknowledge what you're going through. They didn't care enough to look back and make sure you're okay. And that's all you need to know about them. That's all you need to close that chapter of your life and start a new one.
