Endless abyss of unspoken words (Poetry)

Unspoken words I've never told you, they create an endless abyss inside of me. If I could tell you, I would, but I know this is the point of no return.
Who was the bad one here, was it me or was it you? I never wanted this to happen, but who was I to prevent it? And what would you think or say now if you read it?
