You need not always follow what was said by the couple, but note how he said it. You see, a couple who is destined to always be imitating each other's language. The more often he's imitating speech patterns, even the terms that you create yourself, the more you are bound to him psychologically. Mutual imitation of the language (called LSM, or language style matching) tend to look at the happy moments, according to U.S. researchers.
"When two people start a conversation, they usually start talking the same way in a matter of seconds," said James Pennebaker, professor of psychology at the University of Texas at Austin, Texas, and one of the authors of this study.
To see how this is applied to a close personal relationship, the researchers analyzed the letters from famous writers, such as Sigmund Freud and Carl Jung, who exchanged letters almost every week during the seven years of their career development.

There are still two more pairs of LSM was investigated, namely the era of Victorian poet Elizabeth Barrett and Robert Browning, as well as 20th century poet's Sylvia Plath and Ted Hughes. The results of a study published in the Journal of Personality and Social Psychology reveals that major changes in mating each pair is mapped in the poem.
"The style of the poetry of sentences in these pairs is more similar during the happy period of their relationship, and less in unison on the way to the end of each relationship," said Molly Ireland, which helped this research.
Now, the researchers were investigating whether the style of language in everyday conversation can also be used to predict the beginning and end of a love affair. Adjustment style has the potential to quickly and easily reveal whether each pair, whether it's romantic partner or a competitor's business-compact psychologically, and what it means for their future together.
