Romantic trajectories are most likely one of the best examples for observing bi-linked effects. Especially for young people who intend to leave home by way of conjugality, particularly by getting married and buying a house, the synchronization of the couple’s two individual life courses is of the utmost importance. Therefore, the meeting of two “sweet spots” in professional careers is necessary to identify the best timing for leaving the parental home through entry into conjugality. Since professional and personal lives, or external contextual circumstances, can go wrong alternately (or even simultaneously), years can pass before this double temporal “sweet spot” is found (Nico, 2011: 277).
Additionally, later in life there is management and effects between couples for the transition to retirement (Denaeghel, Mortelmans e Borghgraef, 2011).
Love has theoretical importance and is an element of social action and social structure (Goode, 1959:38), often representing turning points in life courses.
Consequently, it may act as a trigger for exiting the parental home towards a conjugal cohabitation (functioning simultaneously as a longitudinal and extra-linked effect, due to the creation of a new household), or, for example, towards a more individualized housing trajectory as a result of the end a loving relationship.
