How to understand this sentence: separated by understanding, combined by misunderstanding.

Wow, it is so strong upstairs. Typing speed 1 min, over 600. Still very Zen! Tell me my personal opinion, but it's not that profound. First of all, "separation by understanding" should have two meanings. 1. Because two people know each other too well, they lack freshness. After knowing each other for a long time, their enthusiasm decreases, and some temptation variables (large forests) will naturally alienate them. 2. Because after careful understanding, they may feel unsuitable to be together. This may be due to living habits, temper and family circumstances. . . . Wait a minute. Why? Besides, "combined by misunderstanding" probably has the following two meanings. 1. Many fates are born in mistakes, and mistakes are variables. You may have met her in the wrong car, you may have mistaken her for someone else, you may have chased her friend, but later you found her better. In short, misunderstanding is not necessarily a bad thing, but a kind of fate. This sentence denies that the combination itself is right and should be a summary after breaking up. Or he thinks his initial thoughts, expectations, fantasies, etc. Because you're all gone now.
