You know this is the way they are and it is so frustrating because you think, maybe this time they will get it together and stop lying. I truly believe it is like when a child lies and they have to cover each lie with another until it feels like a good story. It is almost as if they are creating an altered reality that they want to live in. If you buy it-they win and if you believe it, it must be true. Unfortunately, the longer I allowed him to lie to me the longer the drama continued. It hurt to tell him not to speak to me until he could stop the lies. I had to do that and what would you do if your child lied? You might ask them to go think about it again and come back when they were ready to admit the truth. I would be the same way. The sad thing is some lies become so entailed that you can ask for details on a later date and clearly see they weren't honest...but what you do once you know they are lying will determine the outcome.
