Divorce
Earlier people got married to live together "in bad and good times until the death separates" them. Nowadays each third marriage finishes in divorce. For years the church was against divorces because marriage was considered to be an inseparable union made in heaven. Moreover it was not right from the moral point of view. Everything changed in the second half on the 20th century, in 1960s. Presence or absence of children doesn't influence the frequency of divorces anymore.
If the partners lost the so-called harmony in the relationships and don't want to pretend that they are still happy, they separate. Very often they do nothing to save the marriage that fades. Some couples come to mutual conclusion about the necessity to separate. In such case they stay friends and can even continue to communicate and to meet in the place of the common friends. For the couples couples, where the decision to divorce was not taken by mutual consent, the divorce process can be very long and tiresome. There are situations when ex-partners separate like enemies and the legal procedures on separation of common property may take a very long time. Unfortunately in such a way children become victims of their parent's quarrels. The trial may ask the child to define which parent to stay with. This is a very difficult decision and the child may get a psychological trauma. As a rule, such kids have problems with their own families in their adult lives. That is why parents should feel responsibility for their children when they get divorced.
