Today, in our liquid and mobile lives people are confronted by a complex array of choices, catalysing individuals to construct a mobile nature of the self (Beck and Beck-Gernsheim, 2002). This opens out a plurality of lifestyles across distances at different times, for example, the living apart together (LAT) relationships, where people choose (or are forced) to live apart from their partner but still keep a close couple relationship. In this sense, the emergence of LAT relationships challenges the assumption that intimacy and commitment are thought to be based on physical 'closeness'. However, some empirical studies (Baldassar et al., 2007; Holmes, 2010) indicated that couples are able to enact certain behaviours in order to maintain their intimate relationship across distance and different time zones. Drawing on 39 in-depth interviews with Chinese heterosexual people in LAT relationship, this paper examines 'mobile intimacy', centring on the role that mobile technology play in changing the balance between communication and spatial distance. Considering that distance prevents practical care, each party, in particular the woman in the couple relationship, has a strong desire for receiving alternative support, for instance, 'emotionally participation' or 'emotional intimacy'. I argue that there have significant gender differences in terms of to what extent people want to disclose themselves emotionally, or express love and intimacy with absent others. That is, women are talking more but receiving less emotional support from their male counterparts.
