Now in her 20s, she started driving lessons with Watson when she was aged 17 and while living in foster care.
She described herself as "vulnerable" and said he befriended her, offered her somewhere safe to stay, but then "became obsessed" with her.
"He would follow me, he would spread lies about me, send me cards in the post," she said.
"If I said I wanted to be left alone he’d send me pictures saying he’d end his life."
The stalking escalated further when she reported him to the police.
"I saw him at the end of the road, sat on the corner. I caught him outside my house looking through my bin."
After he was arrested he was released on bail, which she says is when things "just got worse".
