The impact of physical distance and migration on family and intimate ties has long been of interest to family and intimate relationships scholars. Some research stresses that the increasing geographical dispersion of people in globalization undermines intimate bonds and commitments, while other research emphasises that family and intimate relationships are particularly resilient to distance (Holdsworth, 2013). In particular, family migration research has widely shown that support, intimacy and affection can persist with relatives living far apart (e.g. Baldassar & Merla, 2013; Parreñas, 2005). This chapter stresses that actors not only adjust their family and intimate relationships in response to spatial constraints, but set the boundaries of their families and core personal networks in various ways, with consequences for their spatiality. In other words, we sustain that individuals have agency in constructing and reconstructing their family environment, and in so doing shape the geography of their families and core personal networks. In this perspective, the central issue is not so much the impact of physical distance on personal relationships, as we have done elsewhere (Viry et al, 2017). It is rather to better understand the various ways in which individual actors reconfigure their family and intimate relationships in globalization, which entail important consequences for the spatiality of their families and personal networks.
