Why didn't Meng Yun choose Liu Ye or get back together with Jia Lin in the movie Ex-4?

I think Meng Yun didn't choose Liu or get back together with Jia Lin in the movie Prequel 4: Early Marriage because they all realized that this relationship was over and they embarked on a new life path. They choose to respect each other's decision, say goodbye to their past feelings with dignity, and bravely welcome their future life.

The main reasons are as follows:

1. End of relationship: After a series of misunderstandings and quarrels, the relationship between Meng Yun and Jia Lin has gradually faded, and both sides realized that this relationship could not be restored. Even if Meng Yun and Jia Lin meet again, they can't go back to the sweet old days.

2. New feelings: After Meng Yun left Jia Lin, he met Liu Shu and started a new relationship. Although Liu Er may not be the true love of Meng Yun, she has brought new life and happiness to Meng Yun. In this case, Meng Yun doesn't want to give up his current partner for the past feelings.

3. Responsibility and maturity: characters experience in the film has grown and matured. Meng Yun realized that his feelings for Jia Lin had become a thing of the past, and he didn't want to hurt Liu Shu because of his persistence. Similarly, Jia Lin also realized that both she and badon min had reached a crossroads in their lives and chose different paths.

4. Decent Farewell: At the end of the movie, Meng Yun and Jia Lin chose to say a dignified farewell and respect each other's decision. They understand that feelings are sometimes not black or white, but need to be put down at the right time to make each other live better.
