Short Poem: Why?

I cannot forget, but whisper your name
when thoughts of romance within me inflame.
All suitors I meet are mem’ries of you.
I cannot forget, though we are all through.

Get out of my head, get out of my heart.
That day when you left you did not depart.
The love that we had has moldered in me.
Get out of my head and let me go free.

What has now begun, I wish it would end
and life soon return, my heart shortly mend.
But never, I fear, th’infection will die,
and all I can ask: My question is, “Why?”
