What made you fade away

I remember feeling the rhythm of the beat of your heart
All the while knowing our ways were meant to part
Opened up to you, baring every inch of my soul
Now I regret ever letting you this close

I watched you throw away my dear memories
Your departure forced me back down on my knees
For months I prayed, killing time
Hoping you would throw me a rope that I could climb

You moved on leaving me torn and broken
My heart became almost impossible to reopen
And now after all these years have passed,
Please tell me what made you fade away so fast.
