Marriage roles

Traditional classification of roles in a family obliged a man to provide his wife and children with things necessary to live and be responsible for their safety, whereas the woman had to take care of the house, children and her husband’s comfort. The situation had changed since women started working professionally. The distinction of roles stopped being obvious and predefined. Married people have a choice now of making decisions together how they want their relationship to function independently from any outside influences and social expectations on their roles, however it is like that only in more modern countries. 
 
How psychology define a role terminology?
Social role as a social category is a collection of expectations from surroundings (a family, social groups, an institution). This role determines one’s social status and its place in a social group. Every role has set of entitlements but also responsibilities, which we need to make our priorities.
Every human already has a scheduled role which means that the roles can be sometimes contradictory to people’s wishes and life expectations.
