Venus says they are 'still friends off the court and go to dinner but we just weren't getting any results.'
Venus lost in the first round of Indian Wells with Frenchman Benoit Paire and his ranking has slipped to 40 just three places ahead of improving Kiwi number two Marcus Daniell.
The Kiwis have teamed up for a tilt at the Miami Open, another Masters 1000 tournament where they are touch and go to get in.
They have to sign in tomorrow by 6am New Zealand time and hope their combined ranking of 83 is high enough for the 32 strong doubles draw. Last year's cut off in Miami was 75.
Venus and Daniell will return to New Zealand after Miami to prepare for the Davis Cup tie against Korea in Auckland early next month.
Meanwhile New Zealand women's number one Marina Erakovic is off to a winning start in Miami.
The 29-year-old Aucklander has won her first round qualifying against Britain's Naomi Broady 7-5, 6-4.
Erakovic has struggled so far in 2017 failing to get past the first round at WTA Tour level.
Her ranking is 107 and she needs to boost it inside the top 100 to guarantee a main draw appearance at the French Open in May.
She will next face 20-year-old Canadian Francoise Abanda and needs to win two more matches to make the main draw.
