'I'm a good mum, a good wife and I feel no guilt whatsoever'
Rachel*(49) is married with a teenage daughter. She's been having an affair with an older man for the past two years.
'I feel brilliant," she says. "I feel great. And I feel no guilt whatsoever. The affair is making me happy, and the other person happy. I'm not robbing anyone or killing anyone. I'm a good mum, a good wife and a good homemaker. I work as well. I'm just getting a bit of 'me' time.
"It's a beautiful relationship," she says.
"The love-making is brilliant. He's so connected to my body. He knows it better than I do, and he's so caring. I could get 20 texts a day and three emails. Coming up to Valentine's Day I get a love poem every day.
"I look good. I've a bit of a tummy, but that's OK. I'm working with a lot of young people, and one or two of them would have an eye for me.
"But I would not be interested in younger guys. They have no brains.
"I feel better than I did in my 30s. Back then my daughter was hanging out of me and I had to organise my life around her. She's older now. She's often away for the night. I've got more selfish. I'm looking after number one."
But what if you got found out?
"It could be the end of my marriage, but that doesn't fill me with panic. The biggest problem would be the ripple effect.
"I know his family and he knows mine. And I'd be devastated for my daughter. But it won't be discovered. We're clever."
Don't you worry about getting older?
"Not at all. I'll feel powerful. I don't look my age. And I'm like a good bottle of wine, getting better with age. My mum is in her 70s and she looks amazing. If I look like her I'll be fine.
"But I'm not worrying about it. I'm living in the here and now."
