Drawing on in-depth interviews conducted during 2002-03 for the Australian Family Formation Decisions (AFFD) Project, this paper probes the relationship formation experiences of 115 women, men and couples of family-forming age living in eastern Australia. Contemporary relationship formation is characterized by a mixture of ambivalence and resignation to having limited control over the process on the one hand ('if it happens it happens'), and urgency on the other, especially among women seeking to fulfil maternal ambitions in their thirties after prioritizing other things earlier in their adult lives. For most the process of partnering involves trial and error, with timing - finding someone whose expectations of a relationship match one's own - posing a major challenge. It gives rise to a common phenomenon, the 'too soon syndrome', where relationships with many positive attributes are abandoned because one party perceives the other as too keen to 'settle down', and/or himself or herself as not ready to do so. The paper also examines impediments to partnering, including traditional ones like shyness; negative trial-and-error experiences; the demands of study and career establishment; pursuit of agendas emphasizing travel and enjoyment; sole parenthood; and parental marriage breakdown. A framework is provided by Beck's (1992) concept of reflexive modernization, and his associated proposition that life has become highly individualized with an emphasis on creating 'do-it-yourself' biographies.
