There are many names and terms for betrayal in a relationship; infidelity, adultery, unfaithfulness, cheating and illicit affairs are but a few and according to modern studies this type of behaviour is showing an increase.

If you follow modern trends then the likelihood of any partner being involved in an affair has increased over the years.

Evidence found through recent scientific studies show that both males and females are inclined towards infidelity, so are these trends really so surprising?

American Universities have carried out wide ranging studies, interviews and research over a number of years and have determined that infidelity is indeed rising.

Some of this research suggests some very interesting and surprising changes in the demographic of who are more likely to be unfaithful.

Infidelity appears to be on the increase among older men and young couples, with younger women appearing to be cheating on their spouses nearly as often as the men.

There are various theories put forward by the experts as to why more and more people are appearing to cheat on their partners.

The ability to extend an older persons sex drive and sexual health through the use of drugs like Viagra and treatments for erectile problems, could be a possible reason or reasons why they enter into an affair.

With younger couples the availability of internet porn is affecting sexual attitudes, changing preconceptions of what previous generations thought of as normal behaviour.

It does not matter what they use to start their relationship, it can be through emails, instant messaging, social networking sites or mobile phone and the way it will progress is that they will get closer to the other person they are in contact with and you will be left feeling that your relationship is getting more distant and isolated.

Whilst infidelity rates do appear to be rising, the mainstream opinion still says that adultery is wrong and most people do not appear to be unfaithful.

Any data gathered is open to interpretation and may not take into account the possible reasons why there is an increase; it could be that a relationship was in a bit of trouble or that it is close to failing and may actually be remedied with proactive analysis from a marriage guidance counsellor.

One of the other positives that was garnered from all the research is that couples are claiming to be having sex more often, with an average of 58 times a year.
