Unexpected changes in programs

If your wife's schedule changes markedly, whereby she seems to spend too much time away from home, this is something that you should take a closer look into. Does she seem to have unusually high rates of overtime? Does she seem to be involved in other activities outside the home, or does she seem to enjoy spending most of her time with other friends? These are warning signals that something has changed in her.

Unusual Internet activities

You may notice that your wife erases the history of all her Internet activities. No one would really go to this trouble unless there are some sensitive private details. If your wife does not want you to know what she has been doing online, it is because she has something major to hide. You should still not jump to conclusions. She may simply be planning a surprise purchase for you! However, such behavior should warn you.

Change in use of the phone

Your wife may gradually get fond of taking her calls in private where you will not be able to hear her conversations. This will be even more suspicious when she selects the calls to answer in private or she tries to hide particular numbers. She may also start deleting all her call history and text messages. This shows she is hiding something from you, and there are chances that it could be an affair.

Changes in your sex lives

This does not automatically mean that she will starve you of sex as you would expect. While this is common, your wife may go to the other end of the spectrum and engage you with more sex to distract your attention. Whichever way your sex lives change, you should take note.

Loss of interest in your life

While your wife may have been previously very interested in your life and would ask about how your day has been, she may no longer seem to care. She may not ask about your day to avoid the situation where you ask about her own day in return.
