    In this paper, we modify the classical exponential two-sex model accounting for pair formation and separation so as to study implications of the assumption that the divorce rate is positively affected by the amount of singles in the population. We show that the single population pressure on the established couples alters the exponential behavior of the classical model in which the divorce rate is assumed constant. In particular, the total population size becomes bounded and a unique positive equilibrium exists. In addition, a Hopf bifurcation analysis around the positive equilibrium shows that the modified model may exhibit sustained oscillations.
