Body language is one of the most telling factors when it comes to catching people in a lie. If you know him or her long enough to worry about lying then you probably have a good understanding of their regular mannerisms. People who lie usually show signs such as restless, erratic behavior. They may become twitchy or attempt to avoid being in your presence once they start to see that they’re showing such obvious ticks. Keep and eye out for them and you may see a lie plain as day.

"Relationships are built on trust and you have nothing without it."

People who tell the truth generally have no problems bearing their soul to the people they care about. They say the eyes are the windows to the soul so look to them for a glimpse inside. If someone is avoiding your gaze, it may be an attempt at being evasive about more than just a glance. Don’t let them off the hook. Make them look!

Even the most accomplished liars often don’t flesh out their stories enough. With some careful digging, you might just find out more than you bargained for. You’ll know how to do this properly if you’re a fan of cop shows. Think of it like an interrogation. Run your questions by them once then rephrase and run them again, looking for more detail. You might find that the story doesn’t always add up. The truth, on the other hand, is always dead on.

If you’ve got someone on the run in the midst of questioning, they may have to think on their feet. It’s very hard to create a story off the top of your head when there’s a great deal of pressure to make it sound believable. Look for pauses in speech where he or she could be trying to buy time to come up with something to say. These gaps are often huge signs that someone’s story is far from the truth.

When you begin to push someone who’s lying for details, you may find that they try and throw the ball back in your court. Suddenly you may be on the defensive, reeling to answer questions as to why you want to know so much or facing accusations of a lack of trust. People get defensive when they’re cornered. Liars don’t like to get caught in lies. However, this isn’t time for you to back down. Turn up the heat if someone has the nerve to come at you. Don’t give up your position. Catching someone in a lie is difficult at best. If you’ve already started the ball rolling you had better keep it in motion as the next time you try and bring it up he or she will be in a much stronger position to fend off your questions.

The problem with reading these signs is that you may not know for sure whether or not someone is feeding you lines. The good news is that you probably don’t have to. Relationships are built on trust and you have nothing without it. Once you start to question someone you’re with, you know you’re on shaky ground. If all the signs seem to point to a lie then you can basically guarantee that there’s no future for the two of you because you’ll always be left guessing. That’s no way to build a future with someone you’re supposed to love.
