Sackville-West continued to receive devoted letters from her lover Violet Keppel.
She was deeply upset to read of Keppel's engagement.
Her response was to travel to Paris to see Keppel and persuade her to honour their commitment.
Keppel, depressed and suicidal, did eventually marry her fiancé Major Trefusis, under pressure from her mother, though Keppel made it clear that she did not love her husband.
Sackville-West called the marriage her own greatest failure.

Sackville-West and Keppel disappeared together several times from 1918 on, mostly to France.
One day in 1918 Vita writes that she experienced a radical 'liberation', where her male aspect was unexpectedly freed.
She writes: "I went into wild spirits; I ran, I shouted, I jumped, I climbed, I vaulted over gates, I felt like a schoolboy let out on a holiday ... that wild irresponsible day".

The mothers of both women joined forces to sabotage the relationship and force their daughters back to their husbands.
But they were unsuccessful.
Vita often dressed as a man, styled as Keppel's husband.
The two women made a bond to remain faithful to one another, pledging that neither would engage in sexual relations with their husband.

Keppel continued to pursue her lover to great lengths, until Sackville-West's affairs with other women finally took their toll.
In November 1919, while staying at Monte Carlo, Sackville-West wrote that she felt very low, entertaining thoughts of suicide, believing that Nicolson would be better off without her.
In 1920 the lovers ran off again to France together and their husbands chased after them in a small two-seater aeroplane.
Sackville-West heard allegations that Keppel and her husband Trefusis had been involved sexually, and she broke off the relationship as the lesbian oath of fidelity had been broken.
Despite the rift, the two women stayed devoted to one another.
