Okay this isn't really a poem..but it's too long...
A girl once walked up to a boy and asked, "Do...

I wish I could tell you,
but for now I'll have to wait...

You didn't appreciate me
And you took me for granted...

Roses are red
Violets are blue...

As I look into your eyes
I wonder where it all went wrong...

I liked you a lot
But you made me cry...

I hate me
I hate you...

I loved you once
I loved you twice...

You thought you could come along
And try to take my man...

If a picture is 1000 words
How much is a tear...

When I look into your eyes
I see tha loving there...
