Only Two People Can Keep a Secret if One of Them's Dead

I specifically remember
this one thing you said,
only two people can keep a secret
if one of them's dead.

So I lie here awake
everynight in my bed,
cursed by the thoughts
you put in my head.

I guess it's my fault,
I must've misread.
I was so obliviouse,
and you were so far ahead.

I swear I hate you.
I want to see you gush red.
I long to watch the fear in your eyes
as you hang onto life by a thread.

All the blood that I've bled;
All the tears that I've shed.
Do you even know all the pain that you spread?
I know you don't, you're a god damn plague.

So now I lay here
thinking in my bed;
And I've come up with a conclusion
that you're cursed instead.

Only two people can keep a secret
if one of them's dead.

I think I understand now,
I know the meaning in what you said.

A secret is only safe in one persons head,
so that's why fate's left you; to your suicide you'll be wed.
And when that day comes,
not a tear from me will be shed;
For I will be free,
and you my dear will be dead.
