Feeling left out could affect your finances.

A new series of studies has found that the fewer friends a person has, the more that person will make risky financial decisions.

People with more friends tend to play it safer. Researchers theorize that people who feel more socially isolated may take financial risks in order to fill up some kind of inner need that people with lots of friends already feel they've fulfilled.

Having a strong social circle means someone is surrounded by people who will help and protect them.

The bottom line - don't make big financial decisions after you've had a falling out with friends or a breakup.
