Dr Emily Grundy, from the University of Essex, UK, explained that women in relationships have to put in more effort and labour than men, so being in a relationship amounts to quite a lot of work.
"There's evidence that women spend longer on domestic tasks than men and I think they also do more emotional work – so they still do more housework and cooking and things as well as more emotional labour," Grundy told The Telegraph.
She also expressed that men tend to rely on their partners, whilst women are more likely to have close friends and social circles.
"Certainly, there's a common finding from a lot of studies that women who don't have a partner tend to do more social activities and [have] more friends,” Grundy added.
