.1) She pays more attention to her appearance. 

Women who start a new relationships often become obsessed with their looks. According to Top 10 List, it is almost certain that your girlfriend is cheating when she suddenly changes hairstyles, starts wearing new scents, buys new clothes (especially sexy lingerie) and starts working out more at the gym (never did before) Assuming that she hasn’t started a new job or had some other big change in her life, take these changes as signs
.
2. She becomes vague about her whereabouts
 
Studies show that it is very common for unfaithful spouses to be very cold about their whereabouts and activities and will make up preposterous excuses to make up for it. If your girlfriend or wife suddenly has difficulty giving an answer about where she was or what she was doing during the day, it may be a sign that she’s seeing someone else.

3. She is more argumentative and irritable towards you
. 
Cheating girlfriends or wives for that matter may become highly argumentative, nit-picky and defensive.  Top 10 List warns that a girlfriend who starts arguing over the small, nitpicky things may suggest that she  has been cheating and looking for a way out of your relationship.

4. She is not interested in having sex with you. 

The amount of sex a couple has may decrease for many reasons, including busy schedules, depression, stress, and lack of goodness in life. However, infidelity may also be a major factor. Studies show that because emotional attachment is the key for many women in their sexual relationships, some cheating girlfriends or wives may exhibit less desire for their men because they feel emotionally removed from them.

5. She started working more
. 
A classic sign of infidelity is when your girlfriend or wife starts working more–a lot more than she did before. Research shows that this suspicious change in work schedule can manifest itself in different ways: leaving the house earlier to go to work; coming home later than typically; or claiming to have many business dinners (a load of bologne). Take note:  do you see a pattern to these extra working hours? Even so, that may be a sign that something is wrong. Keep in mind that if the job is new or she has recently received a promotion, there is no need to immediately suspect that she is seeing someone else.

6. She keeps jealousy in check. 

Don’t delude yourself into thinking that your woman would never cheat and don’t rush to judgment either; if she is guilty of committing any signs on the list, perhaps it’s indicative that something is awry in the relationship. In any case, this is a great opportunity for you to address problems you may not have noticed before scanning this article.

More importantly, don’t let what may just be a bad case of jealousy taint your perception of her. Reading her the wrong way or jumping to conclusions can permanently sever a relationship; get all the facts before you confront her.

7. Family Detachment 

One sign that she may be cheating is that she detaches herself from your side of the family family. She may also stop hanging out with your friends and family as well, giving you some of the lamest excuses ever. The reason women do this is out of remorse or guilt. She feels guilty about cheating and will feel less pain if she does not immersed in your life- including family or friends. Remember, the less mental baggage she has holding her back, the easier it will be for her to commit the deed.

8. She develops a mysterious friend.

Peter Spalton, also known as ‘The Dating Doctor’, says that women who cheat will often create superficial friends to throw suspicious partners off course. He says: “You may find that she goes out with these friends regularly, maybe the same evening each week. She might even come up with a reason, maybe work or a hen party, so she can stay overnight.”


9. She becomes more secretive.

If your partner becomes increasingly secretive out of the blue it’s one of the obvious signs she’s got something to hide. He says: ‘She has her phone on silent vibrate and carries it with her all the time. She gets up when you’re both watching television in the evening to go to the loo and. takes her phone with her. She. seems anxious and gets agitated if you ask her if everything is all right.’


10. She carries a new scent.

Scent is another important sign of a cheating partner, but if she suddenly starts wearing a new fragrance, the alarm bells need not to go off right away.  She might be simply trying to spice things up in your relationship or sex life, depending on how well it goes.  Going off the deep end too soon could damage your love life — and may lead to divorce. However, if you smell another man’s cologne on her clothes, hands or neck, then she may be planting her lips where she should not. Watch out.

all the above reason can be attributed to something completely different than cheating. the only way to know that someone is cheating on you is IF YOU CATCH THEM IN THE ACT
the reason why so many people fail in r&ship is because they follow such nonsense list instead of enjoying their r/ship.

someone can start to pay more attention to their appearance because someone call them ugly.
someone can be vague about their whereabouts because they are doing something you dont like (can be anything than cheating)
someone can start to be argumentative because they are fed up with you domineering self.
someone can lose interest in sex because you are not a caring lover.
some can start working more because they need the extra money.
etc etc etc

We are saying the same thing.
That's also why they are called 'signs'
Thats the reason for the clauses in the write up, in the case where there may be an exception. This signs are things done recurrently.
How can your girlfriend find it difficult to tell you about her whereabouts day in, day out... Does she suffer from memory loss

This signs also applies to the guys too...

^^^we are definitely NOT saying the same thing. you are claiming that if your partner does any of the stuff that you posted above then this is a sign that he/she is cheating, while i am telling you that the only confirmed sign that your partner is cheating is if you catch her/him in the act.

here are simple clues as to why a partner wouldnt want to tell you where they were:
- because they dont think they should give you an explanation of their whereabouts (like some police interrogation).
- because they believe that it is none of your business.
- because they have a life and can go and do what they please without having someone (who lacks trust and with low self esteem) checking up on them
- because he/she went to sort a very personal/family matter that doesnt concern you.
- because they want to surprise you.
- because they are meeting a childhood friend that you dont approve of.
- because she/he went to a place that you dont approve of (casino/bar/strip club/football match/shopping/girl night out etc)

as you can see above, there are many reason why someone wouldnt tell you where they were (and thousands more), and only a very low self esteem/insecure person would AUTOMATICALLY think of cheating.

Mr Brown..... Then a person that thinks like that shouldn't be in a relationship he/she should live a single life until he/she learns that avtelationship is all bout sharing, and sensitivity to a partners needs and fears and insecurities....?(SMH)

If a partner exhibits those things, they are SIGNS.....I'd they are caught red handed, they are no more signs, it becomes proof.....
First of all understand the meaning of signs and get off my back.....

I think MBJ wants to go into the law profession and he comes here to practice.
op, i don't like lists. There is something they call INSTINCT!

soft and sweet: Mr Brown..... Then a person that thinks like that shouldn't be in a relationship he/she should live a single life until he/she learns that avtelationship is all bout sharing, and sensitivity to a partners needs and fears and insecurities....?(SMH)

if i have offended you then accept my apologies. i am just giving you a man's opinion on your points, if you didnt want anyone to debunk your points, then you shouldnt have posted them on NL as if they were FACTS.

anyone who accuses their partners without concrete proof shouldnt be in a r/ship, as the foundation of any r/ship is TRUST and HONESTY. yes some partners are insecure and have fears, but that shouldnt be the reason for anyone to lower themselves to their levels. what kind of sorry life do you want people to live, if they have to tell their jealous insecure partner where they have been AT ALL TIMES?!

what you should have written is that these signs "could be" that your partner is cheating, but they are certainly not confirmed signs that she IS cheating (understand the difference between a CONFIRMATION of cheating and a POSSIBILITY of cheating)......... but then again, if i think like you do, then your partner leaving the house could also be a sign that he/she is possibly cheating, duh!

MrBrownJay,the Op is on point they are signs and not confirmed....
When you feel sick, with headache and fever. They may be signs of malaria but not confirmed until medical laboratory testing.. It could be thyphoid or something else for that matter.. So signs are not conclusions..

^^ if that is the case, then as i wrote earlier, the OP should have wrote that these are signs that your partner MAY BE cheating.....and not signs that she IS cheating. understand the difference?!

just like feeling sick with fever and headaches MAY BE signs that you have malaria...and not signs that you HAVE malaria.
