Why do girls break up because boys are boring or tired of playing, and boys never break up for this reason?

Girls are very, very changeable animals. He likes to play with boys who have feelings for him. If he has no feelings, he will give up, give up. A girl is a very, very fierce, unsympathetic and heartless animal. She will give up her boyfriend who is not fresh to herself, no matter how pitiful he is. Boys may just have a kind of sympathy and a poor mentality. This kind of boy is the most sad, because to let go of being good to others is to be cruel to yourself. If a girl breaks up, he won't be very sad. He will soon find another spare tire to fill himself and comfort himself. Boys are often the saddest people, and he often thinks that girls are the saddest people. It is often because of this wrong understanding that he feels sorry for that girl. In fact, in love, more boys are often injured.
