Dear Native Speakers,
When the two people in a couple spend a lot of time together, in a positive scenario, they are shaping themselves and the other person in a way that with time they become much more efficient in carrying out tasks together, organizing their life etc. After a while, they cooperate better and function together more effectively and smoothly. What expression, noun or verb is there in English which refers to this process?
What is happening to the 2 people? Could you, please, help me? Thank you.
