Giving up on love

My heart is locked away thousands of miles under the sea
Where there can be no heartbreak
A barren wasteland of bad memories
Through, light can not past
Remains in darkness lurking in its own captivity
Many locksmiths have dove to the ocean bottom
Creating replica keys to open this cell
Momentarily, my heart feels free
Time passes until the key presents its true identity
And back to the abyss I revert
Each time buried deeper in the sand
Hidden further from sight
In time my heart will disappear
And reappear, cold-blooded
Leaving trust in abandonment
Without love for the opposite sex
