Growing Apart

I've been thinking about you lately,
can't get you off my mind.
Been thinking about those memories,
the ones you've left behind.
Why did you leave me here alone?
We were supposed to conquer the world together.
Guess you don't want me anymore,
didn't think there was an end to our "forever."
Trying hard to forget the memories
that seem permanently branded in my heart.
What happened to us,
how did we grow apart?
