Right now, almost a third (28%) of Brits know their partner would rather stay in than go out on Valentine’s Day, but aside from the one-day romantic celebration – how well do people really know their partners?

The data, taken from a new study, by greetings card marketplace thortful, explores the inner secrets of relationships, revealing the things people claim to know about their partners, as well as the secrets they have never shared themselves.

Although 37% claim they feel completely happy in their relationships and know everything about their other half, 13% wish their partner opened up more, prompting thortful to create a guide on the right questions to ask a partner, that go way beyond knowing their birthday or favourite film.

From dating histories, to fantasies, the amount of people on their magic number list, deepest secrets and everything in between – how well do you really know your partner?

What do people claim to know about their partners?

Starting with the basics, the most popular attributes people claim to know about their partners include their hobbies, interests and birthday (64%), as well as their favourite food and drink (62%), and their career aspirations (51%).

However, just one in 10 (10%) claim they know their partner’s party trick, only 11% are aware of their go-to karaoke song, just 18% know their other half’s most embarrassing moment and only 24% know their favourite memory with their partner. On a deeper level, Brits aren’t aware how their partners feel about the following:

  • How much they value your relationship (53%)
  • How they spend their time when their partner isn’t there (56%)
  • Whether they want children (65%)
  • Whether they want to get married or not (70%)

But could they be hiding something?
