Good evening. When I had an online relationship with a girl, it was my best relationship. It was interesting for us to communicate on different topics in correspondence, because we were not burdened with routine affairs. We didn't quarrel because we always shared only the best moments and supported each other sincerely when it was necessary. It was perfect. But over time, we realized that we wanted something different from life and ended the relationship. So far, I have only good impressions of online relationships.
