Today's long-distance love can be done with only one mobile phone. It is the mentality and practice of young men and women who advocate romantic love to strengthen understanding and maintain feelings by telephone. Generally speaking, this kind of love can't stand the test of a long time. If one party can't contact in time because of work or other things, or even always miss the appointment time, over time, it will make the other party suspicious and psychologically unstable. At this time, as soon as something happens, it will make all kinds of assumptions. Love tragedies often occur in life because of suspicion and self-distrust.
