The beginning of a relationship is almost always accompanied with hopes that partners would continue to love and support each other in the days to come.

Unfortunately, many times such hopes are belied and relationships run aground. Here are the ten most common reasons why people break up and couples drift apart.


Mutual love and trust are the foundation for a meaningful relationship in a mainstream monogamous society.

When a partner indulges in an extramarital affair, the action strikes at the very heart of a relationship which is often unable to cope with the emotional and practical consequences and heads towards breakup.

The strongest proof of how infidelity is the most common cause of a breakup lies in the rising divorce rates in modern society.

Even though us government statistics1 put it at a rather conservative estimate of 3.6 divorces per thousand populations, so much is without doubt that marriages breaking up are more common now than ever in America.

And one of the most common reasons for divorces is extra marital affairs. According to a statistics gleaned from 2004, the highest percentage of divorces – as much as 27% – in the US are caused by extramarital affairs with family strains and then marital abuse coming at the second – 18% – and third – 17% – most common reasons for divorce respectively.

In yet another study2, more than 25 percent of the women said that their husbands’ unfaithfulness was a factor in their divorce.

If so many marriages are breaking up mainly because of infidelity, its impact on non-marital, monogamous relationships is bound to be even larger where the legal and family ties of a marriage are absent.
