I wouldn't fess up.


Sorry but that's just me, I'd tell him to get over himself because I'm sick of the same topic coming up for 5 years.


I would also tell him that if he just can't drop it for whatever reason, amd he expects me to accept that, then he must just accept that I will be ignoring the question from now on because I've answered it already.


Why?


Well because I smell a rat too and no good can come from this.


It's like he's itching to grab hold of something to hold over your head. If he knows you lied (which it seems he does) why not just accept it (since it has nothing to do with him) and move on since you haven't changed your story in 5 years? That would be the healthy response... Instead it's like a mini obsession he has.


No good can come from telling him what he wants to hear, I would bet my salary on it. (And I live paycheck to paycheck)
