Elizabeth I said this quote

“ (Response to King Erik XIV of Sweden's proposal of marriage:)[W]hile we perceive ... the zeal and love of your mind towards us is not diminished, yet in part we are grieved that we cannot gratify your Serene Highness with the same kind of affection. And that indeed does not happen because we doubt in any way of your love and honour, but, as often we have testified both in words and writing, that we have never yet conceived a feeling of that kind of affection towards anyone.We therefore beg your Serene Highness again and again that you be pleased to set a limit to your love, that it advance not beyond the laws of friendship for the present nor disregard them in the future. ... We certainly think that if God ever direct our hearts to consideration of marriage we shall never accept or choose any absent husband how powerful and wealthy a Prince soever. But that we are not to give you an answer until we have seen your person is so far from the thing itself that we never even considered such a thing. I have always given both to your brother ... and also to your ambassador likewise the same answer with scarcely any variation of the words, that we do not conceive in our heart to take a husband but highly commend this single life, and hope that your Serene Highness will no longer spend time in waiting for us. ”
