Am I?

"I have loved you for a very long time. Perhaps I have loved you for as long as we have known each other. Perhaps I fell in love with you at first sight.
It's been so long now that being in love with you has become a part of me.
Just like breathing or sleeping, I keep loving you.
Everyday.
Without fail.
I dont know how to live without this love. Maybe, it's toxic but I never cared.
My treacherous heart has always told me, one day he will come to me.
So, I'm waiting for that one day.
Waiting as you keep loving and forgetting other people like any other man in his twenties does.
Fate has been cruel to me.
But I know you will love me.
At the end."
