a positive and original book on the couple

Finally an original book on the couple!
It must be put off by the look "American" style. The author is someone extremely seriously. He created a "love lab" in which he asks couples to spend a few days and observes what happens, which can predict the longevity of a couple.
What we learn such interesting is that one of the keys to success is the ability of a couple to emerge from conflict. There are disagreements disputes, it is quite normal. the issue is an out quickly and well, without rancor.
We leave a bit of all cream pies on the "emotional communication" genre, "Darling we need to talk. That's what I feel" etc.
Very informative!
