He’s never had a relationship. Ie never had a relationship that lasted beyond a few months, never moved in, never met parents, never said he loved anyone (I asked if he’d ever loved someone after I found out he’d never had a proper relationship, to which he said ‘I got to a stage where I thought I might be able to love x (name of a previous date of a few months).
He’s never introduced anyone to his family, never met anyone’s family, never even been on a holiday with someone, not even for a weekend break.
We get on well but before I found this out (a month or so after meeting), I’d noticed he was incredibly awkward in messages, very very formal (always signs off with his name which I know people do but generally not after you’ve got to know someone?! Maybe just me...). He’s very procedural, would never throw in a flirty comment. When together he’s good fun, very good sense of humour (at least I like it!), but again formal and reserved. Often catch him staring into space and he says oh I’m just thinking... nothing wrong with any of this or course, it’s just unusual. He had a couple of relationship books on the book shelf, one of which was a step by step guide to meeting and talking to women, including advice on what to wear, what to say, how to progress a relationship 
I guess that’s not a problem in itself but someone who has gone out of their way to buy a book on relationships but has never been in one for forty years makes me apprehensive.
I’m just not sure what to do as I’ve had many men mess me about and I’m getting older now, want to settle down so if he’s a hiding to nowhere I want to get out now. I know nobody from the internet can decide for me but just wanted to talk it over I think!
