Why can men restrain their feelings?

Because most men are more rational and women are more emotional, it is easier for men to control their feelings than women. Women sometimes give up everything for feelings, but it is irrational for men to give up such behavior.

A man has to restrain his feelings because of his responsibility, and sometimes the expression of feelings will become the reason for others to attack him.

Men have stronger willpower than most women. If a relationship is doomed to have no result, men will refuse more decisively than women. Sad mood is certainly there, but it will not be immersed in such mood for a long time.
