In this post-modern society, the group of singles is constantly growing. The studies conducted in Poland and in the West show that there are primary reason which are most often mentioned for being single. Unwillingness to live in a relationship is most often caused by a fear of losing freedom and being dependent on the needs and expectations of the other person [Stein, 1975; Steig, Jones, 2002]. This fear is accompanied by a focus on a professional career which is easier when one does not have to take a partner into consideration. Marriage or stable relationships are believed to be incompatible with personal development and accomplishing professional goals and ambitions [Kuhn, 1955; Stein, 1975; Grzeszczyk, 2005]. The studies also show that some of the singles do not count out the possibility of having a relationship in the future. This group wants to achieve a stable financial situation and financial independence before they set up home [Stein, 1975; Lichter et al., 1995; Steig, Jones, 2002; Crompton, 2005; Żurek, 2008]. Another reason for being single is the high, or sometimes even unreal expectations from a partner, and waiting for an ideal – meaning true and romantic – love [Kuhn, 1955; Steig, Jones, 2002; Paprzycka, 2008; Żurek, 2008]. When it comes to modern single women, they are young, well-educated and independent, and do not want to be brought down to the traditional role of a woman in a relationship [Grzeszczyk, 2005; Paprzycka, 2008].
