The latest Official for National Statistics figures revealed that 4.8 per cent of couples, around one in twenty, called their relationship "extremely unhappy" in 2014.
3.5 per cent said that their relationship was "fairly" unhappy that year. Both figures are more than double what they were four years previously.
Government figures also revealed that the number of couples who called their partnership "perfect" fell significantly in the same period.
In 2010, 9 percent of couples - nearly one in ten - called their relationship perfect, compared to six percent four years later.
Katharine Hill, from Christian charity Care for the Family, told Premier: "Sometimes we treat them a bit like consumer goods.
"My phone broke recently and I went to the shop and they said, 'you just need to upgrade for a new one,' and I think that thinking has crept into how we treat our relationships."
And speaking on Premier's News Hour Harry Benson, a Christian and the research director for the Marriage Foundation, said: "We all go through ups and downs and the idea that you're going to be in a relationship that you might deem perfect for the whole time is just implausible.
"We say our wedding vows, 'for better, for worse,' for very good reason."
