In a sign that the saga that has gripped France for weeks is not about to drop off the agenda, politicians across the spectrum have displayed an unusual willingness to voice their opinion on what Hollande's handling of the affair and its messy aftermath indicate about the character of the head of state.
The verdict, from his political rivals at least, has not been kind to the portly 59-year-old president, who has found himself in a similar position before.
He left the mother of his four children, Segolene Royal, for Trierweiler after an affair that biographers say was conducted in secret for years before he owned up to it.
Nathalie Kosciusko-Morizet, a leading light in the opposition UMP, warned Hollande that women voters would not quickly forget the dry manner in which he announced that the relationship with Trierweiler was over in a statement said.
"I felt like I was reading a sacking letter rather than a break-up one," said the deputy who is bidding to become the next mayor of Paris.
Jean-Luc Melenchon, the leader of the Party of the Left, added: "His statement was that of an oaf. You just have to read it ... me, me, me."
Even an ally of Hollande said the president had dealt with Trierweiler ruthlessly after denying for months that he was having an affair with actress Julie Gayet.
"As soon as the Closer revelations came out, Valerie was treated like a trickly political issue, to be dealt with coldly," the ally was quoted as saying by the Journal du Dimanche.
Two other prominent figures, National Front leader Marine Le Pen and the centre right deputy Henri Guaino, have accused Hollande of first promoting Trierweiler to a quasi-official role before "repudiating" her in the manner of a medieval monarch.
"It was the head of state who put Madame Trierweiler at the centre of our institutions and installed her at the Elysee -- inevitably this affair is a public matter," Guaino said.
Trierweiler meanwhile began carving out a new role for herself on a long-planned trip to India for the Action against Hunger charity she is associated with.
Snapped cradling an ailing child in a Mumbai slum, Trierweiler was given a sympathetic reception in India and revealed that she plans to continue charity work rather than returning to her previous role as a political journalist for weekly glossy Paris Match.
