Still, I believe statistically speaking, those couple who reunite after a divorce are a minority. The rule of thumb when comes to divorced people is they usually end up being happier initially, because they could not stand to continue to spend their time with one another, those who really suffer the consequences of divorce are children, who sadly become part of the conflict between both ex-spouses.
It is wishful thinking will automatically learn something from getting divorced and realize they had a better live when there was someone they loved in it, stubbornness and selfishness are very strong flaws which cannot only trash a relationship, but also keep that same relationship from having a second change to blossom.
