Elliot Gadzikwa, who is 27, didn't have to say anything when he went to court on Saturday.
Gadzikwa is said to have looked through his wife's phone because he thought she was cheating on him.
He found messages between his 26-year-old wife, Rumbidzai Mudzipuri, and the person who has since died.
Gadzikwa is said to have tricked the man who has since died by acting like his wife and inviting him to their home.
The person who has since died went to their house.
Gadzikwa hid in the dark outside.
When the dead person went into the house, Gadzikwa ran in as fast as he could.
He tried to get away, but Gadzikwa stabbed him in the neck, and he died right there.
Gadzikwa and Mudzipuri both ran away from their home.
The police found the bloody clothes Gadzikwa was wearing and the phone he used to lure the man who has since died.
