How many Britons say they have ever cheated on a partner?

There are two main ways in which people can be cheated on: physically (i.e. sex with someone else) and emotionally (i.e. forming a deep emotional or romantic connection with another person).

Which is worse: sexual cheating or emotional cheating?

Britons tend to say that they would find sexual infidelity worse than emotional cheating. Four in ten (40%) say it would be worse if their partner had a sexual affair where they didn't have feelings for the other person, than if they had an emotional affair where they weren’t having sex with the other person (25%).

While men are much more likely to say they would be more bothered by a sex-only affair (46%) than by purely emotional cheating (20%), women are much more divided, at 35% and 29% respectively.

Can it be ok to take back someone who has cheated?

Britons are divided on the prospect, with 37% saying there are circumstances where it is reasonable to take someone back after they cheated, while 41% draw a hard line, saying it is never reasonable to do so.

This is consistent with previous YouGov findings which suggest older Britons are much less inclined to rock the boat when it comes to potential relationship drama and break ups.

Men are also more likely to think it can be reasonable to take back someone who cheated (41%) than women are (33%).
