A wife has told how she has put her husband on a lifelong sex ban and tracks his every move, after discovering he had cheated on her after taking a lie detector test. Despite his infidelity, Haley and Kev Mulholland still share a house in Bristol, though Mr Mulholland has to sleep on the living room sofa. The mother-of-eight says that while she does not want her husband, she does not want any other woman to have him either. Haley Mulholland became suspicious husband Kevin was having an affair after reading his Facebook page . Mrs Mulholland monitors her husband’s movements, checks his phone and even sniffs him to see if she can smell another woman’s perfume. 'I might not want Kev, but I don’t want anyone else to have him either,' said the 45 year old, who is mum to Sophie, 27, Kerrie, 25, Kasey, 14, Brittany, 13, Paige ten, Tyler, nine, Madison, eight and five-year-old Alexius. 'I keep tabs on his phone and on his Facebook page. He swears he’s staying true, but I couldn’t trust him as far as I could throw him. Over the past few months I’ve become quite the detective.' Though Mrs Mulholland has so far found no evidence to suggest he is straying, she refuses to take her husband of 15 years back. She said: 'While we’re not divorced, we’re not together. There’s no kissing, sex or anything like that, though Kev’s tried his luck. 'He creeps into my room saying the sofa’s given him a bad back and that he needs to sleep in my bed. I just tell him where to go. Kevin and Haley, who have been together for 15 years, are pictured on their wedding day . 'The other night he started stroking my thigh. I slapped his hand away. This body is well and truly out of bounds.' The Mulhollands' marriage became rocky shortly before they renewed their wedding vows on Valentine’s Day in 2013. Mrs Mulholland said: 'A month before the big day I was on the computer and noticed Facebook was still logged on to Kev’s profile. 'I clicked on his inbox, and discovered a message from one of our neighbours. 'She’d written "Have you told her yet?" which made my heart race. 'Had my Kev been going round for more than a cup of sugar? 'The rest of their correspondence was harmless enough, so I decided to give Kev the benefit of the doubt. Haley learns that Kevin did cheat her on after a lie detector test on the Jeremy Kyle televsion show . 'But just weeks after our wedding I started hearing rumours about the two of them. 'I asked Kev if something was going on and he denied it. But I smelt a rat - a love rat.' That is when Mrs Mulholland started to doubt her husband and put him on a sex ban until he admitted the truth. She said: 'I trusted the people who were telling me. So I told him, no nookie until I get to the bottom it. 'Two years went by and I stuck to my word. We slept on opposite sides of the bed, absolutely no touching. Haley says she has banished Kevin to the sofa after learning that he cheated and has also imposed a sex ban . 'By the end Kev was so desperate for some hanky panky he suggested we went on the Jeremy Kyle show for a lie detector test. 'I booked for us to go on the show. A couple of nights later I checked Kev’s Facebook inbox and felt sick to my stomach. 'There were loads of messages from this other woman. She had written that she was worried she’d caught an STI from Kev. It was absolutely disgusting.' Mrs Mulholland went round to confront her neighbour who claimed her Facebook had been hacked. But the lie detector test on the Jeremy Kyle show revealed that Mr Mulholland had cheated on his wife with their neighbour. The couple trip the light fantastic after renewing their wedding vows just one month after Haley discovered the incriminating Facebook message suggesting Kevin was having an affair . The couple kiss after renewing their wedding vows before friends and family . She said: 'Kev walked off stage, swearing that the results were fixed. But that evening he finally admitted the truth. 'He said it had only lasted five minutes, but that didn’t matter to me. Once a cheat always a cheat. 'I knew we were over but I didn’t kick him out for the sake of the kids, instead I moved him downstairs. 'The little ones are none the wiser.' Mrs Mulholland said she has now started to track her husband’s movements to make sure he isn’t seeing other women. 'It sounds crazy as, hand on my heart, I do not want him back. But whenever he goes out I make a note of how long for and calculate what he could be doing,' she said. In happier times: Haley and Kevin who is father to six of her eight children . 'Maybe it’s jealousy or perhaps it’s because I want him to suffer. 'I know his Facebook password and I log in most days to check whether his floozy has been in touch. 'She’s kept quiet, and if she has any sense she’ll continue to do so.' It’s not just technology Mrs Mulholland uses to try and catch her husband out. 'The other day I hugged him as soon as he walked through the door. I think he saw it as progress, but I was just seeing if I could smell another woman on him. 'I make sure I know where he is at all times. 'So far he has passed the test, but if he ever fails I’m ready to pounce.' Mr Mulholland, who is unable to work due to a bad back, has told his wife he will win her back by remaining celibate until she changes her mind. He claims he’ll show he’s remained faithful by doing another lie detector test. Haley Mulholland says she now keeps tabs on her husband and checks his Facebook page . Mrs Mulholland said: 'I don’t know what I’d do if the results came back and he’s telling the truth. Maybe I’d take him back, maybe I wouldn’t. 'For now I’m happy being single. I don’t see a man in my future and I’ll be damned if there’s a woman in Kevin’s. 'He’s made his bed and he has to lie in it – alone.' Mr Mulholland, 46, said he was determined to win his wife back. 'I love Haley more than anything, no other woman compares. The kids and her are my life. 'I’m still living in the house, so there’s still love there. I’m not having sex with anyone to prove just how serious I am. 'The fact that she’s checking up on me tells me that she cares.'
