As an everlasting expression of love, je t'aimerai pour toujours is a promise to love someone forever.
Her final word on herself rings true, " Toujours tourmentee des choses divines."
In the conflict between her sense of what was morally just and her sense of duty to the state she laid herself open to the scoffing taunt of Frederick of Prussia, who said that in_the first partition of Poland elle pleurait et prenait toujours.
Another famous love poem by Victor Hugo is Aimons toujours!
This phrase is even stronger than je t'aime toujours.
