Can someone tell me what this cold joke means? Thank you! !

This is a psychological game between men and women:

It is estimated that at the end of the relationship, the man has no feelings for the woman, so in order to keep the man's heart, the woman used pregnancy as an excuse to temporarily keep him around. Moreover, the man has no intention of looking back, so it is absolutely said-ligation (if the man is ligated, there will be no sperm and the woman can't get pregnant).

The woman is afraid that he thinks he is cheating and doesn't want to be with himself, so she says "joking". When the man saw that the woman had given him a step, he would not let the atmosphere get too stiff, so he said, "I was joking, too."

In fact, the truth of the matter is: men want to dump women, and women don't want to let men turn around on the pretext of pregnancy, but they fail!
