here is a question....

before you decide to lie to her... ask your self which one will hurt her more a lie that might make her smile for 2 seconds or a truth that will hurt her for a couple of seconds but then make it better.... and if she loves you she will understand whatever it is you need to lie about if you tell her honestly.... Good luck

i suggest you write her a letter ask her for help and next time before answering think of what you are going to say.... i've had a lying problem before got in DEEP trouble with it but just sit with her open up to her just no lies for one evening for one hour anytime tell her how much you love her how much you need her and tell her you understand she is fed up but tell her you need her help and support... its a big challenge once you are addicted to it... its hard to go back but i believe you can do.... after that it feels nice believe me if you ever need to talk bball_gurl_19@hotmail.com you can always talk :D

I don't know if this will help you, but there were some recent scientific findings about people who have a tendency to lie a lot.
