Tell me why this blade is stained with blood?

I did cause I never felt loved.

Don't get your bat wings in a twist!

Roses are black,
Roses are red,
People think I'm alive,
but I'm not I'm dead!

Out of all the tears I shed when I was blue,
All of them were because of you.

Darkness awaits you,
and some day you'll get a call.
But when that day comes,
a little blood must fall.

As the thorne of your love pierces my heart,
From this Earth I will soon depart.

Bleeding forever in an eternity,
Will be Hell on Earth with just you and me.

At your funeral I leave a black rose on your casket,
You said you loved me but now you've left.
What am I suppose to do?
One final question but do I dare ask it?

Can I die and join you too?

Out of the blood,
That has been shed.
You are alive,
When you should be dead.

On your gravestone,
Written with blood.
Encircled with a heart,
Are written the words:

True Love.

On your gravestone lays a black rose all alone,
Sitting by itself on the cold engriven stone.
Engraved on the front, says something but I don't know why.
The words that are written say:

True Love Never Dies.
