First, communicate first. First of all, girls should never hold back, doubt themselves and deny themselves. They always wonder if the other person doesn't love themselves because of their own problems. In fact, if they really love each other, it is impossible to refrain from talking to each other and to be indifferent to each other. Therefore, most of the reasons for this situation are because of the other party. You can communicate with him first, and two people will explain the situation. You should clearly point out the problem between you two, point out what he did wrong, and then ask him what he means.
Second, solve the problem. If he says that he is just busy recently, or feels a little tired from work and study, he is a little indifferent to you unconsciously, but his love for you has not changed. In this case, you can actually choose to trust him and let him make a change. Look at his actions, there is no need to say goodbye in a hurry. But if he makes it clear that he doesn't love you, there is no need to solve this problem or pester him.
Third, break up decisively When the other party clearly expresses that he doesn't love you, in fact, his behavior belongs to cold violence, which is the usual means of some boys with bad personality. First, cold girls, girls can't stand it and break up with boys. It seems that girls broke up, but in fact, boys forced girls to break up in this cold and violent way. So if the other person makes it clear that he doesn't love you, then there is no need for you to recover. Say goodbye decisively and welcome the next one. Never deny yourself, you have no confidence.
