Mankoko (41), who presents Ditla le Meso on Thobela FM, separated from Mathe (32) after accusing him of cheating on her with a bevy of women.
The velvet-voiced radio presenter, who played a cameo role in the SABC1 soapie Skeem Saam, moved out of their marital home in Polokwane's posh suburb of Bendor in December.
This was after she discovered a picture of another woman on her husband's phone.
The couple started dating in 2013 and got married a month later.
It is believed Mankoko confronted Mathe of Dunamis House of Worship, a Limpopo-based church operating from the Tshwane University of Technology's Polokwane campus, about the picture.
Mathe sent elders from his church to intervene at his house, but Mankoko allegedly snubbed them and told them nothing was going to stop her from leaving her husband.
According to a friend close to Mankoko, the presenter left her marital home after learning that Mathe was an alleged womaniser, who had more than three kids with different women.
"He did not tell her he had other kids from different women, for that matter," said the friend.
Mankoko refused to comment when approached by Sunday World outside the SABC studios in Polokwane on Thursday.
"I don't want to talk about that matter," said Mankoko.
"Speak to the pastor and call me after 12pm."
But she neither answered our calls nor responded to the SMSes we sent to her.
Mathe confirmed his marriage was in trouble and that Mankoko had moved out of their home .
