There is a fascination people have with emotional unavailability and it's usually to everyone's detriment.
Someone who is not as outwardly expressive as expected, who is withdrawn and not really forthcoming with information, creates a sense of mystery for people. And like any mystery, people want to solve it. And when it comes to someone labelled as "mysterious", people feel a sense of obligation to "solve" that mystery—either to get to know them, to find a way to change them, perceivably "fixing" them, or something similar.
For schizoid individuals, it creates this sense of unwanted attention from people who cannot be satisfied with receiving nothing. At first impression, it's all about the fantasy—look at this stoic person who doesn't pay attention to anyone or care about anyone, imagine if they made an exception for me, imagine if I could get to see their "true" self.
You're not going to get this from a schizoid individual. This is a fantasy you're projecting onto them—that they're something special, something to be saved or explored. Don't expect an emotional response from someone who's frequently emotionally dissociated, it's not going to end up well for either of you.
And it's so common for schizoids to see themselves as not possessing any sense of personality, to be filled with a void. To try to dig deeper against what they're willing to show you, it's violating and can be perceived as controlling or exploitative, which can cause further withdrawal.
I do not speak for all schizoids, but I do speak for myself when I say to not try and make us into something different.
You will be disillusioned and frustrated when the emotionless person is emotionless.
