I think I know the answer to this but just want to check with the MN Jury 
Have been emailing with an apparently-normal bloke on GSM for a week or so. He ticks many boxes - at least from what I can tell from his profile.
But... a couple of days ago we were talking about jobs, and all he would tell me was that he worked 'in government'. That's it. Wouldn't divulge anything more, even when I started to gently take the piss about the fact he was being so cloak-and-dagger about it.
That's a big red flag, isn't it? Surely even if he did have a genuinely 'sensitive' job he'd have a mundane and believable cover story, right?
Or have years of fruitless online dates finally tipped my paranoia-ometer way into the red?
