Minutes later, her two sons Sheldon, 22, and Slade, 19, arrived home from a party. They saw their step-dad getting arrested, his pyjamas covered in blood.
The court was told the couple downed three bottles of Prosecco between them in the hours before Melanie's death.
When police arrived, they found Clark had tried to kill himself with gas and then he begged officers to kill him.
"Melanie Clark had told her husband she wanted him to leave their home," prosecutor Benjamin Aina QC, according to The Sun.
"He couldn't take the rejection and killed his wife. They had been married for 10 years. They had no children together, but she was the mother of two boys and two girls from previous relationships."
