Would you know if your partner was about to cheat on you?
Most of us like to think we would but the signs are sometimes less obvious that you'd think, reports the Daily Mail.
While on their own these behaviours could be innocent, if you're answering "yes" to more than six things on this list, it's definitely time for a talk about your relationship.
People shut up once they're having an affair but during the infatuation period when they think it's innocent and nothing would ever happen, it's very much "She said this and then she did that".
Picture a school kid with a crush on their teacher - and sometimes it is just a harmless crush.
But if they abruptly stop mentioning them, it could mean one or both of them has crossed the line from friendship to romance and they've either stopped the friendship because of it or it's fast moved into an affair.
THERE'S SOMETHING MISSING IN YOUR RELATIONSHIP
Both men and women have affairs to get something they're not getting from the relationship they're in.
If you haven't had sex for the last two years, it's pretty obvious the cute redhead at your partner's workplace who flirts with him is going to be damn tempting.
If your partner's a workaholic and never around and your self-esteem's at rock bottom, you might cheat to get some attention and to boost your self-confidence.
Other people cheat on "perfect" partners for that reason alone: their partner's perfection makes them feel less than perfect.
Some people are searching for something they lacked as a child, others for lost youth.
Whatever it is, few of us realise that's what we're really after while we've got our legs in the air in the hotel room or broom cupboard.
Has your partner talked about something not being quite right? Could be they're about to find what they're looking for elsewhere.
HE WAS IRRITABLE OR DOWN AND NOW HE'S SUSPICIOUSLY CHEERY
It might be because he was questioning your relationship and has cheered himself up by flirting/sexting someone else.
Is your partner more or less affectionate than usual?
More could mean he feels guilty about something, less that he's withdrawing from you.
YOU'RE DOING ALL THE WORK IN THE RELATIONSHIP
The person who gives the most in the relationship - really looks after it and nurtures it - is the person less likely to have an affair or cheat.
Problem is, they can become so fixated on "the relationship" - building a nice home and financial future - they forget the person they're building it with.
The partner then feels neglected and seeks attention elsewhere.
"I was astonished when my husband told me he'd had an affair," said one woman I counselled.
"I couldn't have been any more supportive as a wife. But he said I'd stopped seeing him, as a person. I treated him like a husband not 'Jonathan'. He was probably right."
YOUR INSTINCTS TELL YOU SOMETHING'S WRONG
Most people who seriously suspect their partner is cheating turn out to be right.
If you can't put your finger on it, but you know something's not the same and worry your partner's being tempted elsewhere, trust your instincts.
Particularly listen to your intuition if you're a woman who doesn't have a problem with jealousy. We've got great inner radars.
HE'S TALKING LESS
If he's less interested in talking generally, it could be because he's scared of slipping up.
If he's just become interested in someone else, he'll start volunteering less information about what he's up to when you aren't around.
HE'S CHANGED HIS ROUTINE OR HABITS
If your boyfriend used to run at 5am and now he's running at 7pm, with aftershave on, you don't need to be a rocket scientist to figure out something's going on - or about to.
HE'S CHANGED HIS APPEARANCE
Forget the obvious (the wedding ring's accidentally replaced on the wrong finger or they dropped it down a drain) - look for subtle changes.
Is he hitting the gym and revamping his wardrobe without a word of criticism or encouragement from you? Could be he's out to impress someone who's caught their eye.
HE'S WANTING MORE SEX THAN USUAL
If you're having great sex, your partner can't possibly be cheating, right?
This is called "the hydraulic pump theory": you only have so much energy for sex, so if you're getting it elsewhere, you won't want it at home.
Wrong.
Some people are more passionate at home when they're having sex on the side because the affair arouses them.
However, this alone doesn't mean he's cheating - more sex could also mean your partner has decided to make a bit of effort!
It's rumoured Jackie O found a pair of women's knickers stuffed into her pillowcase at the White House while she was married to Kennedy.
HE SMELLS DIFFERENTLY
If your partner smells impossibly fresh and clean after a hard day at the office, could be the affair has already started (he's had a shower after sex at their lover's place).
He smells of a perfume you don't wear? He might well be rubbing up against someone else.
THERE ARE TOO MANY WEIRD CONVERSATIONS
Is your partner always saying "I'll have to call you back" when the phone rings while you're together?
Do they look shifty and the tone of their voice changes when they take some calls? Being secretive with their phone when they normally aren't is a huge red flag.
It's also not a great sign if your partner's always "popping out for a few minutes".
If you're crying "for no reason", getting headaches, feeling rundown - again, it's your body's way of saying, "Hey, you might not want to admit it. But I know you think they're about to cheat and I'm suffering for it."
Confrontation might not be your strong point but in this instance, it really is crucial.
