The stranger who now lives in my house

I've been lurking on the forum recently, haven't been posting or commenting too much. But something came to me the other day and I wanted to see what you all thought (Both ADHD and non-ADHDers here): 

But for me, I am now fully feeling as though my husband (late ADHD dx earlier last year) is an absolute stranger to me. I couldn't tell you what he likes, dislikes, what his fears are, what his dreams, hopes, plans...nothing. And to be fully honest, he can't really tell mine either because I haven't and CHOSE to not share them. Vunerability breaths intimacy and I won't put myself out there anymore to someone who I don't know and frankly, doesn't treat me with the respect I'd like to have, much less deserve. 

(caveat: I will 100% acknowledge this goes both ways. I don't feel respect towards him. I'm not disgusted by him but I don't feel very fond of him)

But as I'm being encouraged (therapy, group support, friends, etc) to find out what I DO want and need and boundaries and all that.... I'm just perplexed and what to do when this realisation has hit. He's a literal stranger to me. I dno't even know if I want to know him anymore. Because he hasn't and won't grow, he doesn't appear to me to even be open to growing or finding out what's wrong in our marriage or even trying to work on something together - this push will have to come from me and frankly, I am too tired and exhasted from what life has thrown us over the last 10 years. And I can honestly say that in the last year, if there was an inkling that he was open to it or just even behaved in a way that I got the impression that he WANTS to be married and be with me, I might be open to taking that push or encouragement. 
But as Dr John Delony says... behaviour is a language. I don't care what he's said the last 2 years, it's what he DOES and I don't like it. And don't appreciate it and most of all, incredibly confused as to the type of person he has become. A stranger.
