The problem most women have with a cheating boyfriend is finding out far too long into the affair because they don't know the signals they should be aware of. It is also a devastating emotional experience that many women wish to avoid and to do so they hide from the facts that may be right in front of their face. The signs of a cheating boyfriend when taken together should set off warning alarms to any woman who is in a serious relationship.

The thing to remember is that not all of these signs indicate anything is wrong. In fact if you notice just one or two it may not mean anything but when they become a pattern of behavior it may signal something is wrong. Recognizing this early in cheating affair can save you from the heartache and pain that a longer lasting affair can bring.

One of the first things to watch for is a change in his work habits. If he is all of a sudden working late or taking business trips when that was never a part of his work schedule it may be a sign that he is actually spending that time with someone else. But you do have to be careful here because if he has been promoted or changed job descriptions staying late and traveling might be something he actually has to do. Communication is a good way to find out the truth in these situations. If you are uncertain just ask him and see how he reacts. If he has nothing to worry about he'll act the part but if he gets defensive or mad about your inquiry into his changed work schedule he may be hiding something.

Sudden changes in his sex drive are also another sign that your boyfriend may be cheating. It can also be a sign of stress or some sort of medical problem but if it's seen in combination with the other signs of cheating there is a good chance he is getting some on the side.

Negative changes in your boyfriend's attitude towards you or a marked defensiveness to your questions about his behavior should be noted as possible clues to an affair. In fact this type of defensive attitude where your boyfriend throws your accusations back at you is one of the more well known signs of cheating. If he has nothing to worry about why is he being so defensive when you ask him questions about where he's been or what he's been doing?

You also need to be cognizant of your boyfriend suddenly being extremely nice to you. Romantic dinners, gifts, and flowers from a man who normally doesn't exhibit this type of behavior could be sign of guilt that follows infidelity. This may be his way of making it up to you while trying to keep his cheating act hidden.

Learning the signs of a cheating boyfriend may not be something you want to do but if you have doubts about his commitment to you it is best to know what to look for.
