In order to collect data, the attitude questionnaires of Vitely (2006), feelings of loneliness by Russell, Pilova and Cortona (1980), interpersonal forgiveness by Ehtshamzadeh et al. Data analysis was done using descriptive and inferential statistics, Pearson correlation coefficient and path analysis (p<0.05).

The results showed that the coefficient of the path between loneliness and attitude towards extramarital relationships is β = 0.319, which is statistically significant at the p<0.01 level. The coefficient of the path between the feeling of loneliness and the use of virtual social networks is β=0.170, which is statistically significant at the level of p<0.05. The coefficient of the path between interpersonal forgiveness and attitude towards extramarital relations is β=0.074, which was not statistically significant at the level of p<0.05 and this path was removed. The path coefficient between interpersonal forgiveness and the amount of use of virtual social networks is β=0.364, which is statistically significant at the p<0.01 level. The coefficient of the path between the amount of use of virtual social networks and the attitude towards extramarital relationships is at the level of β = 0.430, which is statistically significant at the level of p < 0.01.
