Note: A femme fatale tells her occasional lover that she can no longer be his mistress as she has another lover, and wants to be "innocent" (meaning starting anew) while the married lover has plans to make her his (wife).
The first part is from the married lover's perspective that he has found his true soulmate and wishes to be committed to her and make her his wife. The second part deals with the femme fatale/mistress perspective on the relationship and why she can't be with him even though he promises her commitment, happiness, and marriage (it is also implied that he is already divorced). She breaks off the relationship because she has fallen for another lover (implied to be royalty) plus she feels that he's too clingy and emotionally attached.
