Which word describes my feelings?

For how they both so similar are,

Both involve a beating of the heart,

But the difference is the colour.

For love is never be perceived as black,

As hatred so commonly is.

But love is rich and red,

Like blood enhanced with oxygen.

For hate, black blood pumps,

Poisoning he mind further.

For love, red runs through veins,

Adding more poison of a different kind,

Oxytocin.

But how does a mind differentiate the two,

For a heart still beats and blood still flows,

So until that puzzle is solved,

I shall both love and hate you, my dear,

Until death do us part, accidental or not.
