Is She Bored With You?
A wife who cheats often does so because she feels unnoticed or bored at home. These unhappy feelings typically grow very slowly over time. For that reason alone, changes in your spouse can be difficult to detect or even identify. Another obstacle with many 
marriages is that both partners get busy with day to day activities and the relationship is taken for granted and never nurtured. This is normal up to a point, but is important that you take action to save your marriage before it is too late. To prevent your wife from looking outside of the marriage for companionship, be aware of your part in keeping her in love with you.
Reasons for Cheating
The main reasons for arriving at the state to ask, is my wife cheating may be emotional, sexual or financial. In the first case, the problems originate by the conduct of the husbands. Many husbands think that sexual intercourse alone will satisfy their wives. However the expectations of wives are different. They expect their husbands to fulfill their emotional needs. They want to be caressed, loved, and praised by their husbands. If you do not appreciate your wife when she cooks wonderfully or dresses up well and someone else appreciates this there are so many chances that your wife will fall into the set of cheating housewives.
Just Sex is not Enough.
Next is the sexual need. The wife must be satisfied both emotionally and physically during sex. The satisfaction of women completely differs from that of men and unless husband understands the secrets of satisfying his wife, he cannot expect his wife to be true to him. The foreplay in sex is very essential for women and the husband must spend time to get her ready for sex before he penetrates into her. Anything other than this will only result in dissatisfaction because the wife will lend herself to anyone who will satisfy her emotional cravings.

Is the Money Enough Reason to Cheat?
Last but not the least is the financial trouble. You would have heard the cheating housewives say that they develop new friendship for money. They must be educated that the real happiness is not in money. Any relationship that was made merely for money will not last for a longer period. This will only lead the wife to utmost frustration in the end. The new relationship that she has developed for money will last only till the attraction exists. Once it wades off, the person will move quietly. She will soon realize that only the love of a good husband will last forever.
