Bloody hell, if we're going to dissect things in public watch...in first message mention I correct computer programmer's mistakes, pretty much an engineers role. So, moving back to the location, after you'd said you'd lived here too....:
me : 'Oh yes, xxxx is a great place - but it's full of engineers!'
I'd put in an exclamation mark - which I thought was a simple, jokey self deprecation', especially when you replied:
you: 'haha - ex engineers wife!'
which I took as a knowing wink, so replied
me: 'God, poor you!'
Again, with an exclamation mark. We're clearly just not on the same page here, so I think you can all safely cancel the hat orders ladies!
To be honest, I think I'm just confirming to myself exactly why internet dating is such a fraught experience. It's just one catastrophic misunderstanding after another...!
