It was also found that men who played the field got over the relationships when they ended much quicker then women did.
Women who stay single who once had a great love that did not work out tended to be mentally stable.

The fact that women who live with a man without benefit of marriage are not as happy as the men is because there is no financial protection for them when the relationship ends. Security is everything to women and marriage represents stability and although the relationship can end they will have some rights. This explains why women who are married are more mentally stable then if they simply lived together.

Women have children and need a stable lifestyle and a strong desire to protect themselves and their kids. So marriage is very important financially and also there is the question of respect that everyone needs. If a women has her own career and here own money these thing may be less important.

From a man’s point of view and if he’s over 25 security is not very important. But most men don’t want to be squeezed into a relationship by the women he loves. He want’s it to be his idea. The trick for a woman is to make him believe it is His Idea.
Being married has always been associated with greater mental and physical health. Bachelors don’t live, as long, at least that’s what the myth indicates. In the past studies have shown married men live a longer life with greater psychological happiness.

There was an English study for 10 years ending in the millennium of 10,000 adults. Both men and women were interviewed and asked a series of questions about being depressed or anxious.

Long-lasting relationships that have weathered the storm provided excellent mental health.

People that had failed relationships and were now alone had combinations of grief and anger and were often depressed. Both men and women had poor mental health after this experience. But for those who could move on to new relationships, much of the damage was somewhat reversed. Although women seemed to have a harder time of letting go than men did.

Women's mental health progressively deteriorated with the more break-ups they experienced.

For men that had several different experiences it seemed the opposite was true. Men who had more then one relationship and moved on seemed to be in excellent mental health. Those men that had only one relationship and not moved on were not as mentally stable.
Women who never married but lived with their mate were in great mental health unlike men in the same situation
