Far be it for us to promote infidelity, but you can't pretend it doesn't happen. 

Either the match made in heaven with the man of your dreams turns sour, or, for whatever reason, you start looking elsewhere. And funnily enough it happens more often in summer than in winter... 

So here's our guide to understanding infidelity and the rules to stick to if you want to minimise the damage an affair causes. We take a look at why we're unfaithful, and the pros and cons of playing away.

Have you ever been tempted to stray? Tell us what you think about infidelity by taking part in our survey.
