A woman who was harassed for years online has learned the stalker was her boyfriend.

Ruth Jeffery, 22, described the mystery stalker – who turned out to be her boyfriend Shane Webber – as “sick” after he took over her identity and sent naked photos of her to friends and her family, including her father.

Impersonating his girlfriend, Webber sent online messages to people and claimed she was sexually attracted to them, which lead to one man turning up at her house.

He also bombarded her with explicit videos and photos, pretending they were from old schoolmates.

Meanwhile, two-faced Webber was playing the perfect partner, posting loving pictures of him and Ruth on Facebook, telling friends she was the best thing that ever happened to him and boasting: "Ain't my baby beautiful?"

Jeffery was subjected to the ordeal for more than three years, taking anti-depressants during Webber’s campaign of terror and saying she wished at the time she was dead.

Webber denied stalking Jeffery when she confronted him, realising some of the details in the messages could only have been known by her boyfriend.

He pointed the finger at one of his friends who was then arrested.

But Webber was finally caught in June, when he used Ruth's email account to send explicit images of her to her entire contact list.

Jeffery, a Loughborough University student from West Bridgford, Nottinghamshire said: “I want him to be put in prison because he has wrecked the past three-and-a-half years of my life.

“I've known him for 10 years, so in a way it feels like the past 10 years have been wasted. We were really close. We did everything together. I would tell him everything. I thought he was telling me everything.”

She added: "He was pretending to was be a lot of people. They were all saying, 'I used to fancy you, Ruth, and I want to meet up”.

"He created an account very similar to mine and was speaking to people, making out he was me.

"He was sending out pictures of me saying, 'It's Ruth, I really like you. Here's a picture of me, can you send pictures back?'

"I was confused as to why these people, who I thought were people from school, would be sending me these kind of images.

"It made me so stressed because it was happening every single day.”

Webber, from Nottingham, was convicted of harassment by Southampton magistrates and will be sentenced on October 6.

At Southampton Magistrates' Court yesterday, 22-year-old Webber admitted causing harassment, alarm or distress.

The pair first met at school and were sweethearts until Webber dropped out when he was 14.

They got back together in 2007 and unemployed Webber, from Clifton, Nottinghamshire, soon began his campaign of abuse.

After the hearing, Ruth said: "I want him to be put in prison because he has wrecked the past three and-a-half years of my life."

Webber will be sentenced next month.
