One of the best sources for you to gather clues about your cheating wife is her cell phone. Check out the message inbox and outbox. See if she erases the messages on a regular basis. If she does then she is definitely hiding something from you.

If her phone bills are unbelievably long yet she never calls you, it simply indicates that she talks to someone else who is probably much more important than you. Catching a cheating wife is painful, but knowing the truth is always best.
