A study of 147 couples who met through online dating agency Match.com found that 61 per cent had high levels of the three components - and most had been together a year. Around 16 per cent experienced "companionate love", with intimacy and commitment but not much passion. Those who had just met or had not been together long were going through what the researchers from Bath University called non-love, with low levels of all three inGREdients.
Study chief Dr Jeff Gavin said: "To date there has been no systematic study of relationships formed online. Love is an important predictor of success, stability and relationship satisfaction. It is a multi-faceted concept."
