Suspecting your partner maybe having an affair behind your back can be an awful ordeal.
The heart-sinking betrayal can be so overwhelming it can leave those let down by their partners feeling sick to their stomach.
But there’s one private investigator who has made it his job to catch out unfaithful partners – saying most clients looking for help and reassurance are usually female.

Daniel Anderson, from Manchester, says both men and women regularly hire him to snare their unfaithful partners in the act.
He then launches discreet investigations to work out exactly if there is any truth behind his clients' suspicions, Birmingham Live reports.
Cases of cheating partners - dubbed matrimonial surveillance - often keep Mr Anderson busy from Fridays to Sundays, as well as late at night. Pre-matrimonial surveillance is also available for soon-to-be newlyweds looking for that extra reassurance.
Mr Anderson, 38, said: "People don't come to use when they have one small red flag about someone. Often, there is a lot more to it.
"I will always try and prepare clients for it and tell them to go into it with an open mind - hope for the best and prepare for the worst. Nine times out of ten, if a client is getting in touch, and it's a valid reason, they have not dreamt or imagined it.
"We talk about a good instinct - there is something about a woman's intuition." Now, Mr Anderson has revealed some of the signs you may have a cheating partner.
This can include coming home late or staying out longer, being secretive on the phone or a lack of intimacy. Heading straight for the shower after returning home can also be a sign your partner may be cheating.
People should also look out for anything which was previously not a normal activity, such as a new hobby, which then becomes repetitive "all of a sudden". Other signs could be working later or more often, frequent business trips, becoming more conscious about their appearance and passwords changing.
Mr Anderson - who has a background in security and close protection - launched Anderson & Co Surveillance and Private Investigators Ltd in 2019. He first launched in Shropshire and has since opened officers in Birmingham and Manchester, with his work taking him across the world.
Surveillance services into potential cheating partners start from £500 and can reach up to £3,000, Mr Anderson said. The private investigator said: "There's this idea that we hack systems to get information on people but we don't.
"We have access to private systems and databases which we spend a lot of money on, which allow us to find this information. That's all done legally and ethically."
