I Dont Understand. Poem by Chelsea Hansford

Ive tried to find the answers,
But the question's hard to say,
Why am i so miserable,
When i never wanted you to stay?
Why am i still aching,
For what we used to be,
When at the time i never knew,
Just how much you meant to me?
I seems terribly silly,
What is there left to do?
I took our love for granted,
Now someone else is loving you.
I doubt that this is jealousy,
But what else could it be?
I cant believe im dreaming,
That you are comming back to me!
