If you spend several nights a week on the sofa binge watching box-sets with your other half, don’t worry you’re being boring – you might just be securing yourselves a successful marriage for the future.

New research found that the more often couples got together in front of the TV or went to the cinema, the higher they rated their partnership.

Especially among couples who did not have many friends in common, sharing this activity (if you can call it that) strongly predicted greater relationship quality.

Lead scientist Dr Sarah Gomillion, from the University of Aberdeen, said better understanding what works in a relationship can improve our physical and psychological health. He said: “What these results suggest to us is that when people have a hole in their social network that they share with their partners, they might become more motivated to share media as a way to compensate for that deficit.

“Watching TV with a partner or watching a movie you both like is a really easy way to improve relationship quality and anyone can do it at any time so this is something that is good for relationships. It might help us identify an intervention that can improve relationship quality.”

The findings are reported in the Journal Of Social And Personal Relationships.
