How?

How does one love when the person is incapable of loving?
When all of the muscles in your heart try to beat out the feeling of another, but your heart only beats for the one person, Well mine beats from habit now.
I still await the day my heart figures out that it has no reason to beat and just stop, And ill just fade.
But of course that would be all to easy, No, I have to be cursed to live, So I have to try and endure, even when it feels like my heart is ripping out the stitches ive sewn, from all the pretending, Pretending to be happy.
I wish I didnt have to pretend anymore.
