By Wikipedia :
Segregated conjugal roles are those in which the husband and wife have a clear differentiation of tasks and a considerable number of separate interests and activities. Marriages where couples also have separate social ties and obligations tend to be less durable.
By me:
It means that the husbands and wives don't share childcare, the don't take decision together... They don't share their free time together etc.
