- It's human nature not to make eye contact with someone if you are being dishonest with them. Is your wife avoiding making eye contact with you when you two have a conversation? Try looking into her eyes when you talk to her and see what her eyes tell you. If she doesn't make eye contact with you or if she avoids it all together chances are is that she is hiding something from you. More than likely, she is cheating on you. - Is there a sudden change in her appearance? When a couple is married for a long period of time, they tend to be relaxed in appearance. Look for signs of your wife suddenly dressing up more, wearing more make-up, wearing a new perfume scent, buying lingerie that you never see her wear, etc... When she starts to tend to her appearance more, chances are it's not for you. Women always want to look their best when starting in a new relationship or an affair. And many many more!
