According to sociology and through the years, the nuclear family (a heterosexual couple who is married and has kids) has been considered by many to be the "ideal" family in which people can develop in a better way.
In this example, Marissa lives with her boyfriend and their two children, so they are not married. Marissa's parents are disappointed that they are not married. Thus, they are using the classical definition of the nuclear family/ideal family (according to which they should be married) to judge her living arrangements.
