What does the fortune teller mean when he says that my boyfriend and I are the most familiar strangers?

A: The most familiar stranger generally refers to two people who have been in love, owned, understood, cared about and become one after breaking up. But for some reason, I won't talk so freely after breaking up, and the atmosphere is very embarrassing. So the average lover will be like a stranger after breaking up. This is the most familiar stranger. The most familiar stranger also means pseudo-intimacy. In a close relationship, in order not to break the stability of the relationship, avoid the negative impact of conflict, cater to each other, hide themselves, and maintain a close relationship, they have become "the most familiar strangers."
