I am going to take a softer approach then Kris and play the Devil's advocate for a little bit. Could the lies be a reflex survival skill that is resurfacing because of the pressure he is under? It doesn't excuse the lies, it just puts them in a little different context and by trying to understand why he is doing it may make it possible for you to confront him about it in a more gentle and understanding way.

I totally agree that lies are lies and it isn't a good idea to let them slide.
