• If you have noticed some changes in your spouse recently, you might be suspicious of infidelity. However, just because some lifestyle changes occur doesn't mean he's cheating. Be on the lookout for 10 specific sure signs of infidelity before you jump to conclusions. These signs can help you identify a cheater and plan your next move. An article published by the World Psychiatric Association denotes that infidelity from a mate can cause long bouts of depression in the other. Look for the signs so that you can take control of your relationship.
  
  

Financial Changes

• Keep a careful watch over shared finances. Look for unexplained and uncharacteristic charges or receipts from restaurants or hotels. Observe even small trinkets like jewelry or flowers. That money is most likely being spent on someone else. Affairs cost money; spending that the other spouse doesn't know about is a sure sign of infidelity.
  
  

Absences

• Anyone having an affair will find themselves away from the home often. If a spouse suddenly has more conferences to attend for work or starts going away to her sister's for the weekend, it could be because she's having an affair.
  
  

Physical Appearance

• One should be suspicious if a husband has always worn a beard and khakis--yet he suddenly goes clean shaven and wears a suit and a tie. He may be trying to impress someone new. He might also start working out more.
  
  

Conversation

• If a spouse shows greater reluctance in discussing anything important with her mate, this is a sign of an affair. When communication slows down between spouses, it's sometimes because she suddenly has someone new.
  
  

Eating Habits

• If your spouse begins to show a new preference for something he has long avoided, be suspicious. The eating habits of his lover will become his habits, and he'll start eating in a different way while at home, alerting his wife that there is someone else.
  
  

E-Mails & Internet

• If a spouse has a secret email account that the other doesn't know about, this is a sure sign that something is amiss. Also, look for strange Internet usage. It can be a tip off that something is going on.
  
  

Sex

• If a couple has enjoyed a certain pattern to sex--yet all of a sudden the husband wants it more, less or has strange requests in bed--it's possibly because he's having an affair with another woman who has awakened those appetites.
  
  

Physical Evidence

• Don't be blind to evidence, such as jewelry that isn't yours, a love note or a hotel key. It can be hard to face head on, but these pieces of evidence--when found more than once--denote infidelity.
  
  

Relationship Changes

• If you notice that one spouse or significant other has become more distant with the other, less patient or even is quicker to anger, it could be because she's receiving attention from a new lover.
  
  

Intuition

• There is something to be said for a "gut feeling". If a spouse begins to wonder if the other is being unfaithful, he should look for other signs that one can gather together as evidence.
