What to do?

You're one of my best friends,

But you like me

And have for years.

I've known it all along,

But I can't address it.

I'm taken

And I don't feel the same about you.

So what can I do?

You know me better than anyone,

But I don't love you.

You say you're miserable

I know why.

You don't know I know,

So what should I do?

I don't know what to do.
