Given that the whole point of lying is that you're not supposed to know it's a lie, from the liar's point of view, there really is no expectation for you to have "known" that he was lying.
You didn't "make a mistake" for "failing to identify a lie" ahead of time - he lied, and you accidentally caught him in it, because you believed him regarding something that was entirely believable, and he probably didn't expect you to want to go with him, else he'd have lied and said he was going someplace he knew you wouldn't want to go. He should feel embarrassed for lying, not you for catching him in one.
Side note - polygraph tests aren't nearly as accurate or useful as TV and movies make them out to be.
This actually makes a lot of sense. I like your point of view.
