Maintaining a loving relationship is hard enough at the best of times. But one couples' expert says the rise and rise of online dating is making it even harder to enjoy a stable pairing.
Figures released by charity Relate this week have revealed that one in five UK couples regularly argue or consider splitting up. Between 2013 and 2015, 2.87 million people were described as being in 'distressed' relationships.
"The constant infiltration of social media in your relationship creates jealously and bickering," Jones, a leading sex and dating journalist, told Julia Hartley-Brewer.
"It can also offer a constant carousel of temptation. No one ever posts ugly pictures on Facebook.
"One big thing now is people meet through online dating, but they find it hard to give up. You get this constant ego-boost of people liking you and sending you messages.
"We [also] work the longest hours in Europe in Britain, so you're spending far more time with colleagues [than] family, and that creates distance between you."
So what is the secret to happiness and longevity in a relationship?
"It's about having quality time together," Jones said. "The hardest part in the world is being honest to your partner.
"A lot of people say they're honest, but it's not always true."
