There is no next relationship. Marriage is for life and any divorce and remarriage is adultery. It is either to remain single until the spouse dies, or reconcile.
I'm NOT divorced (I'm very, very happily marriage). But the stats are there.....
In the US,
1. About HALF of those who officially, legally get married will get a divorce. This stat has remained remarkably unchanged for decades. What HAS changed (a lot) is the number who bother to officially get married. So, often the stat is the "separation rate" - those who lived together for a significant period of time and then separate. That stat is around 80%.
2. Of those who get a divorce, 65% of them will get a second one. In other words, getting a divorce significantly INCREASES the chance of another one.
For some time the divorce rate in the USA for first marriages has held at about 50%. This is a national tragedy. This statistic also means that many people have subsequent marriages. Common sense suggests that someone who remarries is older, wiser, more mature, has learned from their mistakes...
