After an argument with the powerful Orléans family, she installed herself at a small hôtel particulier in enclos du Temple, next to the palace of the Grand Prior.

On her husband's death in October 1764,[citation needed] she hoped to marry her lover Louis François, 6th Prince de Conti but in the end had to give up this dream due to his lack of interest.

Among her houses was the fr:Château de La Rivière à Fronsac (which was sold it in 1794).

On 7 July 1794 the 70-years-old was arrested in the height of the Reign of Terror together with many other nobles,[1] but acquitted after the trial in September (1 Vendémiaire).

[2] She wrote several poems and works of literature: Her son Louis-Édouard de Boufflers-Rouverel (1746-1795) married Amelie Constance des Alleurs.
