Abstract
The subject of the research presented in this paper is the impact that engagement treated as
a change in the life of a couple has on the communication in the dyad. The identified dimensions of the communication are following: support, commitment and depreciation. All presented dimensions are based on the Marriage Communication Questionnaire by Plopa. The location of the individual's results on these continuums is important for his functioning in a love relationship, and thus indirectly also for achieving life satisfaction. The results show an inverse relationship between the length of the relationship and the dimension of support toward a partner (result at tendency level) that can be explained by an increase in the sense of loneliness along with the growing length of seniority in a relationship.
