College students are generally between 17-23 years old, and their physical development is mature, and their desire to communicate with the opposite sex is increasingly strong, which contributes to the universality of college students' love. Although college students are basically mature in sexual and physical development, their psychological development is relatively backward. The psychological development of college students is closely related to education level and society. Most of them are from school gate to school gate, primary school, middle school and university, with little or no contact with society, and the correct outlook on life has not been fully established. In addition, due to the lack of sex education in our country and the prejudice of society and family against sex education, many college students lack sexual knowledge, and because of the maturity of their bodies, they lack proper psychological preparation and correct psychological guidance for sexual desire and sexual impulse, resulting in a confused or confused psychological state [1]. The immaturity of college students' psychological development determines their incorrect view of love and inaccurate grasp of the timing of love, which leads to many blindness and instability in college students' love, which is also the most fundamental reason for the problems of college students' love.

(B) the immature and unstable outlook on life of college students

Although college students' outlook on life has been established, it has not been fully finalized and is easily influenced by the outside world. The formation of a correct view of love needs the guidance of a stable and mature outlook on life, and an unstable outlook on life will lead to an incorrect view of love [2]. At present, college students are in the lower grades of love, especially the number of people who begin to fall in love in the first year of high school is on the rise. Many students do not have a clear concept of their life goals and needs because of their shallow social experience and simple thinking, which leads them to be simple, naive and immature in dealing with love. When choosing lovers, they tend to emphasize appearance rather than inner; In the way of love, the form is often emphasized and the content is ignored; In the act of love, we often emphasize the process, ignore the result, emphasize the pleasure and ignore the responsibility. [3] The immaturity of these love problems is caused by the immaturity and instability of college students' outlook on life. Therefore, it also causes the characteristics of autonomy, idealism and utilitarianism of contemporary college students' love view. Everything about college students is still inconclusive.

I can't bear too many heavy commitments, even if I make an oath, it is likely to be fragile. "Young wings can make you fly higher and farther, but its immaturity can't bear too much weight." [3]

(3) College students' own knowledge level is not high, and their social experience is relatively superficial. Although college students have certain knowledge, ideas and social experience, these are very limited. When college students hand over the "responsibility of choosing a lifetime" to this age prematurely, don't they just find the wasteland harvested prematurely in the mature season? [3] Similarly, the shallowness of college students' social experience will also lead to misunderstanding of their love concept. Because college students have little social experience, lack practical experience in what they have learned in class and books, have low ability to withstand setbacks and resist adverse social and cultural influences, and their consideration and treatment of problems are often divorced from reality, so their analysis and judgment of love are prone to deviation, and they have high expectations for love objects and love endings. However, this kind of love phenomenon will gradually decrease with the growth of grade, knowledge and social experience.
