text: Jason Cotterill sent revenge porn to his jilted lover's daughter and threatened to post a sex video on the mother's Facebook page . A mother whose jilted lover sent revenge porn to her 18-year-old daughter has spoken of the 'absolute nightmare' her life became as he bombarded her with abusive messages. Jason Cotterill, 42, plagued his victim with messages over the internet, even threatening to post a sex video of her on her Facebook page. The terrified woman said her life became a living 'hell' when Cotterill, who was jailed last week, sent an explicit photo of her to her own daughter. 'It got so bad I considered suicide,' the mother said. 'If it hadn't have been for some great friends I would have gone through with it.' 'It wasn't nice for my daughter. It was my past - years ago. My kids didn't need to know about that. 'I was trying to move on with my life. It's part of my life I want to totally erase. 'I know I'm not blameless because I shouldn't have slept with him. It was a stupid, stupid thing to do, it was a drunken thing. But it made my life an absolute nightmare.' Cotterill knew his victim from childhood and knew that she had been previously involved in making sex tapes, Birmingham Magistrates' Court heard. He and the victim had attended the same school when they were children but got back in contact through Facebook in 2013. They met up for three dates between January and September 2013 but had sex on just one occasion. The court was told that the mother - a former sex worker - immediately regretted the liaison and told her lover she did not want to see him again. Soon afterwards she began receiving 'creepy' messages from the defendant, saying he loved her and wanted to be with her. As a result, she 'unfriended' him on Facebook and changed her mobile phone number. During the trial the woman told the court he set up 67 different Facebook accounts in an attempt to contact her after she blocked him on the social networking site. The victim said: 'My life was made hell. I became depressed, anxious and scared to leave the house. Cotterill was jailed for 12 weeks and ordered to not contact woman again following a trial at Birmingham Magistrates' Court (pictured) 'He didn't know where I lived but I thought "What if he finds out?" It got me worried to go out, I was constantly looking over my shoulder. I became very depressed, and the fact that he was sending pictures to my daughter was the final straw. 'It was just constant. There was no let-up. He kept sending messages. Some people said "Oh it's only messages", but it consumes your life. 'They say you should delete your Facebook account but it's a way of keeping in touch with my friends and family, especially friends I don't get to see. I blocked him but each time he set up new profiles to get past it... There was no way he was going to stop.' She reported Cotterill to Facebook but the social media site did not take any action, the victim claims. Cotterill, 42, plagued his victim with messages over the internet, including threatening to post a sex video of her on her Facebook page . Eventually the woman told the police about the messages, ending the abuse, but the court case was yet another ordeal. She gave evidence from behind a screen that was just a few yards away from Cotterill, who smirked as she spoke. 'I thought if I didn't go to court he could carry on doing it, so I got the courage from somewhere,' she said. 'I'm happy I did, but it was difficult. This has been going on since August 2013 so it's nice to be believed. 'It feels like a weight's been lifted and hopefully this will be the end of it.' 'I'm happy the police arrested him and brought him to justice. I hope this sends the message out that you can't do this kind of thing. 'I have no idea how I got through it. There was a point where I was going to give in until a very, very good friend of mine said "You cannot let this man do this to you anymore". She was very concerned about my health, my mental stability. 'The Government has made this sort of thing a criminal offence, and that is a good thing. 'But I think about young children and teenagers who are going through a similar nightmare, and it sickens me. There are people out there who are not strong enough to deal with it.' Cotterill, from Oldbury, West Midlands, was jailed for 12 weeks and had previously been found guilty of harassment following a trial. As well as being jailed, he was also banned indefinitely from contacting his victim. District Judge David Robinson said: 'You harassed the complainant over a three-month period and used social networks constantly in a threatening manner to get her to re-engage with you. 'There are a number of aggravating features in this case. 'You sought to use dozens of Facebook profiles to get in touch with her, you also found a link to a pornographic site and made use of that. 'You either involved or threatened to involve others, sending the link to the woman's friends and her sister, insinuating that her children might get to see the photos. 'You used the power you had over her by the knowledge of those photos.'
