Couples with young children are as likely to stay together if the mother is the main breadwinner rather than the father, new research shows.
A paper published in the journal Sociology today says the relationships of parents are in some cases more stable if the mother earns more than the father.
Dr Shireen Kanji, of the University of Leicester School of Management, and Dr Pia Schober, of the German Institute for Economic Research, Berlin, examined survey data on 3,944 British couples as their first child aged from eight months to seven years.
