What are some signs to look for if you think your spouse is cheating on you?

Signs from the car:
  • They let you do the talking most of the time.
  • They are using more gas.
  • The mileage in their car is too high. Check the mileage for them to and from work. Is there a lot of unexplained mileage?
  • They want you to wait while they clean out their car before you get in it.
  • There are two empty cups or containers for food for more than one person in their car.
  • The music stations in their car have changed.

Signs of Money:

  • Money is unaccounted for (this could also be drugs).
  • You find receipts for items you've never seen.
  • There are unexplained charges on credit card bills.

Here is some more input and advice from people who have been cheated on:

  • If you know that they cheated on people they were with before you, the chances are much higher that they will cheat on you.
  • If you're losing sleep over it and become obsessive and angry, don't just shun it away as paranoia. It might be right.
  • Unfortunately, the "signs" aren't that obvious nor are they that reliable. If he/she is doing it "right", you won't be able to tell unless you catch him/her in the act. In general, if you're the type of person that tries to keep life interesting for your spouse, you'll minimize the potential, but you can't eliminate the possibility no matter what you do. Some people tend to cheat no matter what their home life is like. Were they cheating on someone else when they met you? If so, it's probably an established behavior pattern. If your spouse is the type of person who can be trusted in other areas of life you might have a good reason to trust him in marriage. After all, marriage is about trust and commitment.
  • Note that if your spouse is not cheating and you are constantly being suspicious and questioning everything, you might just drive him/her into being unfaithful.
  • If you believe they're different now, then take the time and think of a plan to investigate them on your own.
  • If you have a gut instinct that they are cheating, 9 out of 10 times you are right. That feeling is there for a reason and if I were you I would check it out. Be careful though, you don't want it to be your own insecurity and be wrong. That will screw things up because then he will know that you don't trust him.
  • The heart knows. Don't let your mind talk you out of it. There are a lot of signs of cheating.
  • Be patient. Don't let them know you suspect them. Plan what to do if they really are cheating on you or lying to you. Be prepared to leave them. No matter how ugly, fat, worthless, or horrible lover you think you are in your mind you will always feel that way if you stay there and don't listen to your gut instincts and the hard evidence. Self esteem is how well you trust yourself. If you know something is going on, and deny it is happening you aren't trusting yourself and your self esteem same will be low. Remember somebody will love you no matter what you look like. There is always someone out there who thinks you are a 10.
  • A spouse often cheats with someone close to both of you, e.g., a neighbor, friend, or even a family member of yours. Are they especially close to someone of the opposite sex?
  • Days without showering at home, but your partner seems to have showered.
