In extremely poor parts of Zimbabwe, some women have left their husbands to travel to South Africa.
“Marriages are fast breaking up with women choosing to stay alone in South Africa’s hotels and lodges,” a villager in southern Zimbabwe tells the Christian Science Monitor.
“But the most unfortunate part, is what are they going to do after the World Cup?”
