The break-up of the French President, Francois Hollande from Valerie Tierweiler was gaining speculation after he was photographed coming out of an actress’s apartment wearing a motorcycle helmet.
A magazine published photos that revealed the probable affair Hollande had been having with an actress, Julie Gayet.
Hollande, who has never denied having an affair with Julie Gayet, had admitted to a "difficult moment" in his relationship with Trierweiler.
Trierweiler spent a week in the Elysee Palace hospital after the revelations. On Saturday evening she tweeted her thanks to the "wonderful staff" at the Elysee Palace.
Adding, she "would never forget their devotion or the emotion at the time of departure."
Toute ma gratitude va à l'extraordinaire personnel de l'Elysée. Je n'oublierai jamais son dévouement ni l'émotion au moment du départ.

Hollande was quoted as saying: "I wish to make it known that I have ended my partnership with Valerie Trierweiler."
He told the state-run AFP news agency that their "shared life" had ended.
Trierweiler, a journalist for the glossy magazine Paris-Match, plans to travel to India to support the French charity, Action Against Hunger.
The two have never married, although she was known throughout France as Hollande's First Lady.
Ms. Gayet is suing the magazine for €50,000 (£41,650) in damages and €4,000 (£3,330) in legal costs, claiming it breached French privacy rules.
Closer magazine said that the affair had begun during the 2012 presidential race.
