The first depends on the future planning of two people. Many college students break up after graduation because their plans for the future are completely inconsistent. For example, if two people come from different places and go to college in one place, but both intend to work in their hometown, there will be a natural estrangement and long-distance love. Or two people choose to develop in different cities, which are all realistic problems that must be faced. Then, in this love, one party will become the victim. When two people don't want to be victims, the love in college will stop here, and they will definitely not get married. The probability of getting married in this case is almost zero.
The second depends on how deep two people are. Many people think that campus love is the purest and most beautiful, but in fact, college students don't have much choice in falling in love. They may be your classmates in this school or even a class. When you go out into the society and meet all kinds of people, you may not feel so deeply about the object of love in college. Of course, there are also feelings that are very good. Even if they are not together, they will try their best to get married. A very good friend of mine fell in love with her boyfriend in college. After graduation, they returned to their hometown, but they got married five years later. We were all surprised at the time. After they got married, their state was different. Until the child was three years old, the woman gave up her job and went to the man's hometown.
The third is that the probability of marriage is particularly high. The career planning and hometown of two people may be in the same place. When many college students fall in love, they like to find their hometown, not only because there will be a group like Hometown Association, but also because everyone will consider getting along with each other in the future and even their future development. Many universities around me are very successful in falling in love because they come from the same school or the same place. After graduating from college, either work hard together or go home together. Many plans are particularly consistent, and there may be relatives and friends around after graduation, so the probability of getting married can reach 70% to 80%.
Therefore, although generally speaking, the probability of college students falling in love and getting married is 20% to 30%, it still depends on the situation, because the probability of their marriage is different under different circumstances.
