The last thing a husband wants to do is accuse his wife of having an affair when in fact she is not. Therefore, if you suspect your wife is cheating, take great care to do things the right way so you do not end up with a damaged marriage. One of the most common signs of a woman having an affair is her spending more time at work, long lunch hours, extra meetings and so on.
You see - the majority of affairs begin at work. The affair could be with an employee, boss, consultant, or client. Therefore, you first want to take note of any special attention pertaining to the workplace. For instance, if you notice your wife is spending more time taking care of herself to look nice at work, leaving earlier than usual, going out every day for lunch, staying late, taking business trips, and so on, then you may have a reason to be suspicious.
Another sign that your wife may be having an affair is that she suddenly takes up a new sport, activity, or some kind of interest. While this could a good thing and have nothing to do with cheating at all, again you want to pay attention. Along with the behavioral change would cove her taking better care of personal hygiene, having manicures and pedicures, choosing a new hair color and/or style, shopping for trendy or sexy clothes, etc.
While the thought of following your wife sounds mean or invasive, if you believe she is having an affair, then you owe it to yourself and your family to know the truth. Sometimes, confirming an affair is hard. In this case, you might need to hire a private investigator to do the work for you. However, if you have time or interest, you can always be your own private eye. Finally, you can even purchase miniature, hidden cameras to place around the house if you believe she is having the man in, buy software that can monitor her computer activity, and a wide array of other tools to help you know if your wife is in fact cheating.
