We live in a world where day after day, they try to prove that friendship with ex-partners isn't just normal, but good, civilized, and progressive. Psychologists think otherwise, and they have reason to do so.
As a rule, splitting up with our lovers, we swear to stay in good relations, keep in touch, not get lost, and come to help. In general, when cutting ties, unless, of course, it's a scandal accompanied by breaking dishes and thrown from the balcony of your mate's stuff, we are honestly going to stay friends and ... stop communicating at all. It turns out that people get lost, even with the warmest feelings for each other, and it's OK. We've discussed everything, figured out all we need, and become strangers to each other in a matter of moments.
