he provided you with the opportunity to "confront" without losing it, by lying.
You can say, "you're right I do TEND to know when you are lying, so I drove by POS's (okay say her name or just say "her")
house and your car was there...Please don't lie to me again, b/c it adds insult to injury and you're better than this, and I deserve better."
THIS IS THE 180 Proof and it's the only reason I support saying anything--to show him that. OTherwise I'm all about just being the better woman/choice.
Don't assume he feels guilt at this point and don't confuse his concern with getting caught (kids blabbing) with guilt either. Remember in HIS mind he is still the primary long suffering victim...
But once you say this--leave the room and
THEN Go out as you planned
and if he asks YOU questions
You COULD say "I don't want to lie so how about I not answer? But I won't be out all night."
or just be vague
