Slowly, could it be that maybe he was embaressed a little that someone he invited declined?
either way you look at it lying is an issue i had to kill a long time ago, while we were still together. i just accept the fact that he will lie. i cannot change it, or control it. once i stopped making a big deal about it, he started making it a bigger deal. now he will constantly tell me right away if he lied about something.
i also tried to thank him every single time he told me the truth when i knew the truth was a hard thing for him to say. i always look for a way to praise him for being honest. "thanks for being honest with me about xxx, it may have hurt a little when you first said it, but now that i think about it, i can do this now. if you would not have told me the truth i would still be doing xxx. and i know it would have been easier for you to protect my feelings by lying, so want you to know i really appreciate it."
i say this so often you would think it would be old by now, but every time i say it, i see a possitive reaction. 100% of the time it works well. and like i said, he is making telling me the truth a huge priority now.
plus i am very much happier looking for ways he is truthful instead of watching constantly for the lies. trust me, i know this is hard, and it takes practice, but for me it worked.
