Before she could escape, the jealous man dragged her inside, threatened her with a knife, kicked her to the floor and stamped on her head and then emptied a full kettle of hot water over her. The Sun UK reports.
Suzanne is still receiving treatment for the third-degree burns and has bravely released photos of her injuries for the first time and also details of what happened.
She reveal that she went out with pals and returned with one girlfriend in the early hours to find her living room window open and McLean inside with a knife.
He jumped out of the window and forced her to open the door while her friend ran for help.
"I was trying to calm him down, but he just wasn't hearing it.
"He started kicking me and I fell to the ground and he carried on with the kicking, and stamping on my head.
"That's when I don't know if I passed out briefly because when I went to sit up he was holding a kettle above me.He poured that directly on my lap, all down my legs and my stomach. I was screaming.
"He said 'do you want another one?' and he went back to the kitchen, but that's when the police came.
"I went straight into shock and then it felt freezing cold. The pain was horrific."It was absolutely the worst pain I have ever been in. It felt like someone was ripping sheets of skin off me but slowly.
"What Jason did to me that night has completely changed my life - I can't even face having a bath as a fear of water still haunts me."
"At first I was angry, and then after seeing him smirking in court all I wanted was to see him get a good sentence and I think he did.
