Dating expert reveals reason people cheat on their partners and the hidden 'red flag' trait you should look for

A dating expert has shared some of the main reasons why people cheat - and it's not always about being unhappy in their current relationship.

It's safe to say that getting cheated on is one of the worst things a romantic partner can do - and yet, it's something that has been happening since the dawn of time.

There's no set reason for why people cheat on their significant others, it usually varies from situation to situation, however, this hasn't stopped dating experts spending their time trying to work out why.

For Australian dating columnist Jana Hocking, she believes there that 'validation' and 'adrenaline rushes' are two major reasons why people cheat.

"I think they take the risk because they think it's sexy or exciting, or the sneaking around is giving their everyday boring lives a bit of an adrenaline rush," she explained on TV show Weekend Today (via Daily Mail).

She then went on to explain that insecurities and a need for validation can also drive people to have a wandering eye, adding that: "There are also a lot of average guys cheating on like ten out of ten girls. That is the common theme.

"I think it's because these doofus guys are thinking "she's so hot and she could cheat at any opportunity. I need that validation to people to still think 'I'm hot as well'.

"It's ridiculous, but it happens."

Psychotherapist Esther Perel has also shared her insights in why she believes partners will cheat on each other, agreeing that not all affairs are born out of poor relationships.

"They cheat for a whole host of reasons that have to do with conflict and discontent and disconnection," she explained during an episode of the Diary of a CEO podcast, adding that this includes loneliness, resentment and a need for external affirmation.

Hocking also warned viewers about potential suitors who appear 'really charming' as it can be a major red flag in a relationship. This may sound a little strange - as most of us want to be wooed in the early days of our relationships - however, Hocking isn't the only dating guru to mention excessive charming as a cause for concern in the early days of dating.

Dating coach Kelsey Wonderlin also noted that a partner being excessively 'charming' in the early days of a relationship can also be a red flag, especially if your new partner also appears full on and it feels like they are chasing you.
