Unusual behavior when your spouse is on the phone is another sign of cheating. When they are talking on the phone near you, do they try to lower their voce or even leave the room? Hanging up a phone quickly is another signal to watch for. Be cautious of increased cell phone use, as many cheaters prefer to use their own personal phones, as opposed to family phones.
In addition to examining the behavior of your husband or wife, the behavior of your friends should also be examined. The friends you share together may start acting differently towards you. This is often because your shared friends might know more than you do. Even if a friend does not outright tell you that your husband or wife is cheating, they may intentionally or unintentionally show you the signs.
These above mentioned signs may be an indicator that your spouse is cheating on you, but there may also be reasonable causes for these behavior changes. For example, your spouse might want to look great for you and you alone, or they also may simply want to improve their health.
Since there are no guarantees that cheating could be going on, even with the above mentioned signs present, additional steps should be taken. These steps can and should include monitoring cell phone calls, viewing the cell phone bill, or hiring a private investigator. Never confront your husband or wife without the proper proof. Be sure to get solid evidence of cheating, otherwise you could be creating a whole new problem in your relationship.
