Over protection of their cell phone and other personal items like wallets or purses. Unexpected or unexplained nights away, at 'Friends'. Accusing YOU of being unfaithful. If they can do it, they will presume you could too. If you're a woman, follow your gut instinct.
IF SINGLE:
Breaking dates
Not keeping in touch with you during the week (usually a guy you are dating will ask you out for the weekend)
Always out with his buddies
Not interested in what you have to say
Doesn't bother to ask what is going on in your life
Isn't interested in your friends
Is lethargic, moody when with you
Doesn't remember your birthday or other special occasions
MARRIED:
The smell of perfume

Calls in the evening and the person hangs up
Phone #'s your husband has and he doesn't explain whose they are
You can always check his emails or any boards he is on online
Receipts from hotels or motels
Keep an eye on your Visa card for any transactions for jewelry, motels, hotels, rented vehicles, etc.
Working more over-time than he use too
Forgetting your birthday or anniversary (some men can forget and it doesn't mean they are cheating, but they will make up for it.)
Not interested in any aspect of your life such as how your day went, if you want to go out for an evening or have friends over.
A lack of interest in you, or having your friends over for a nice evening
Never taking you out for dinner or a movie
These are but a few, but usually, if most women have a gut instinct follow through on it, but be warned, be sure you have proof and don't be the over-zealous type (or over jealous) and ruin your relationship.
Before you jump to conclusions it's type you both brushed up on your communication skills. So sit down one night and have a nice quiet chat and discuss your relationship.

Some signs of cheating are:
But if you think your man is cheating on you, then talk to him about it NO MATTER WHAT. You have to talk to him. And if he says "I'm not cheating on you", and you still feel like he is, then he isn't right for you.

Some outward signs of a cheating partner is a sudden change in his weight (he decides to lose the love handles) - he starts paying more attention to his grooming, may even get a new hair style and/or wardrobe. Being secretive with phone calls or you may start experiencing hang ups - when you answer the phone.
Frequent needs to "run out" for an errand that takes hours rather than minutes or time missed from work with no answers for the absence.
More or less attention to you in the bedroom (sometime guilt makes him more attentive) sudden "new moves" or inability to perform. Saying someone else's name during sex.
Credit card charges that have no explanation. Or buying you gifts or flowers for no reason, that is out of character. (GUILT!)
Spending more time "at work", with no overtime in the paycheck.
These are some outward signs but are not all or not always an indication of a cheater. Unless you have had prior reason not to trust him he deserves the benefit of the doubt -
Talk to him about what you have noticed (without accusing), discuss someone else's cheating partner with him and how you feel about it, ask him what he thinks about the "friend" - watch him carefully when he answers.
Do not accuse unless you are ready to live with the repercussions. It is extremely hurtful to be wrongly accused.
