How to deal with a pathological liar who wont admit there wrong?

..Hi there, First and foremost, you must let this go..This is about him only, not you and he is the one who inevitably will pay the consequences for his lying..Continue to educate your children on the importance of telling the truth, so they in the future will not get caught up in his or someone else's lying as well..You also must understand that this too, is a mental illness, and one he alone will have to get help for if/when he ever recognises it for himself..The important thing for you to examine, is why is this bothering you on the level that it is?..You may want to read up on codependency and how to separate, and keep, your issues from someone elses..Take care..
