This is no justification for betrayal - after all, regardless of motive, infidelity is and will always be wrong. But why she cheated comes down to how your wife's heart and mind works. For her to reject her husband for another man, she doesn't need physical contact with him. She may be cheating emotionally without betraying herself physically. If she feels a lack in her own marriage, she may end up falling for another man's charms.

Watch for some signs these signs:

1. Change in behavior

She'll act like she's hiding something. She avoids looking into your eyes and it will seem like she is keeping secrets with her friends. As you approach, they quickly change the subject. She is always looking at her cell phone and won't ever let it out of her sight.

2. She starts to treat you differently

Women in general are very emotional. If she is in love with another man, she will grow colder with her husband. She'll stop wanting hugs and kisses (and intimacy) with her husband.

Or, the opposite may happen. Because of the infidelity, she may feel guilty, and will try to make up for the betrayal by being much more loving than she used to be.

3. Too much time outside the home

If there's another man involved, your spouse might start to have "overtime" hours at work. She'll also have a lot more to do on the other side of town like getting a manicure or meeting a friend for lunch. She'll be gone for hours at a time and won't ever pick up her cell phone when you call.

4. Sudden desire to look prettier

Women are usually vain by nature, but if they suddenly become overly careful about their appearance, watch out. Of course she's wanted to look pretty for you in the past, but this is different. She'll dress up but it feels distant; she's looking beautiful for another man.

5. Disgust

If she is in love with another man, she may be disgusted with the kiss, the smell, and the intimate moments with her husband. You can tell by her reactions when he touches her. The same is true for a woman; if her husband cheats on her, this woman doesn't want anything to do with him.

6. Criticism

In your relationship, where there was praise is now criticism. Suddenly she to finds your common habits irritating, begins to criticize your appearance, and the way you think or act. These things have never bothered her before, but now they drive her crazy.

7. She avoids talking about her day

She avoids the subject because she doesn't want to go into details and end up contradicting herself. The less it's discussed, the smaller the chance is of leaving holes in her story.

These signs don't mean anything if you notice just one or two. A woman might act differently because her husband did something to hurt her. Or she may be planning a big surprise for you. Even if you see all seven signs, don't jump to conclusions. Have a blunt conversation with your spouse before making assumptions.
