I have ASD and I'm all about the deep stuff, because that - including emotions and emotional subjects - is brain-food, for me; it gives me that nerdy buzz.
I don't want or expect those kinds of chats all the time; I'd find that as exhausting as anyone else would, for all it would be exhaustion from doing something I enjoy. But I do want/need them often enough that I know whether someone's on the same page as I am.
And I doubt I could be with someone who didn't understand the attraction of those kinds of thoughts or conversations; I don't like feeling like a partner doesn't "get" me, which is why I look for as many shared interests as possible. But deep subjects are an overarching interest; they're part of how I'm interested in everything else, so I doubt I could do without them with a partner.
But my problem with partners who don't discuss things like that is mostly what pps are saying. About not knowing whether someone does genuinely want the same thing as you do, or whether they're just going along with it.
I was burned by that again, recently. Luckily I've got to the point with it now where I look for the signs, so I spotted them early enough that I wasn't heartbroken.
The frustrating thing about it was that the guy genuinely thought that he was being nice by being that way. That the fact that I was the one questioning how things stood meant that I was the one being difficult.
If you don't really want someone, and are just going along with something - even when they clearly care a lot about you also wanting them and make sure to check in with you to make sure you're ok with everything - then you're not nice, you're an arsehole.
I'm very confident and can be bordering on overbearing, so I check in with people frequently, especially in the early days. But the kind of person who avoids conversations about feelings and opinions tends to see any enquiry as to their feelings as me pressuring them anyway, rather than something to take at face value, so it doesn't do much good.
Being in your position would drive me up the wall, OP. But maybe I've never met someone who is genuinely fine in all other respects, so I could be being biased by saying that.
