OP, I could've written your post, all except for the 'I don't feel like mine is' part?
I often joke to my DH that words don't actually cost money you know, you can use them!
My DH is most definitely not a chatterbox, but he does tend to think exactly the same as myself about 99% of things, 99% of the time?
We agree on finances/decor/holidays/household chores/TV programmes etc so there's never any real need for many discussions about them?
Even while watching TV together, he might say something like 'Why would she do that, that doesn't make sense?' and I would've been thinking the exact same thing!
It's eerie really, and it made me dump him via email after a few weeks of dating initially, because he seemed 'too good to be true', as if he was just mirroring me? But he really wasn't, and the last 20yrs has proved that.
I know he'll tell me anything, he just isn't naturally 'chatty', and I'm fine with it.
In your case OP, is it simply that he isn't interested in talking to you specifically? Or do you think it's laziness? Or that he doesn't care?
