In my heart the old love
Struggled with the new;
It was ghostly waking
All night thru.

Dear things, kind things,
That my old love said,
Ranged themselves reproachfully
Round my bed.

But I could not heed them,
For I seemed to see
The eyes of my new love
Fixed on me.

Old love, old love,
How can I be true?
Shall I be faithless to myself
Or to you?

Sara Teasdale
