First, it is difficult to give each other a sense of security in a long-distance relationship.
We often hear the saying that distance produces beauty, but if couples are too far apart, what happens at this time is no longer beauty, but constant contradictions and estrangement. If two people are in different areas, the only way to contact is to keep in touch briefly by telephone or WeChat. There are such a group of long-distance lovers around me. They started dating in high school, but they went to different cities and regions because of different universities. Their relationship lasted only a year, and then they broke up. I once asked that girl, and she said that he couldn't give him the sense of security he wanted.
Second, long-distance love will reduce mutual understanding.
Two people fall in love in a long distance, and it is more appropriate to describe it as love. They all contact each other through mobile phones, and we only know each other through each other's descriptions. At this time, their understanding will not be as profound as before. You don't need a reason to like someone, so you don't need a reason to dislike someone. When the understanding between two people gradually decreases, it is inevitable to drift away.
Third, long-distance love is easy to make each other suspicious.
In real life, more and more love tends to be a temporary passion, pursuing a fast-food love, rather than a relationship that you really think calmly and want to maintain for a long time. Long-distance love is the most difficult of these relationships. It is difficult for those two people to meet, and they will be suspicious if they can't get in touch.
All in all, I think long-distance love is really not very optimistic for me personally. Maybe people who really love each other can cross the geographical distance, but such people are only a few.
