In Aphra Behn's poem, On Her Loving Two Equally, she speaks openly about the problems associated being caught between two men, Damon and Alexis.
It seems that Behn finds herself torn--when with one of her loves, she finds herself wanting the other. For her, it seems that she would need both men to merge as one in order for her to be happy given she curses the predicament she finds herself in:
Cure then, thou mighty winged god,
This restless fever in my blood.
Therefore, one could make a very justifiable decision regarding the fact that she really loves neither of them. Behn, if she did love either, would not wish to be with one while spending time with the other man. On the other hand, one could also justify that Behn finds that each man enhances the qualities of the other (but, this would speak to the fact that she does not really love either).
