The result concluded by OkTrends - the research arm of free online dating website of OkCupid - comes from a survey of 833,987 of its 7 million users, reports the Daily Mail.
The study found that an 18-year-old Twitter user has an average relationship-length of around nine months while non-Twitterers - defined as 'everybody else' - enjoy an average relationship of nine and a half months.
But the problem intensifies as the users get older and by the time Twitterers hit 50, the disparity stretches to a two month gap.
The average relationship length for Twitter users at that age is 15 months as opposed to 17 months for 'everybody else'.
"Unfortunately, we have no way to tell who's dumping who here; whether the Twitterati are more annoying or just more flighty than everyone else," said the website.
