If someone perceives you as high status and herself as low status, is insecure or maybe shy, you might feel “out of reach” for her. (IMO “distant” can mean a lot of different things here.)
This could be compounded, if you are confident and e. g. don’t feel the need to fill every moment of silence with chatting, while she maybe does.
But a perceived distance also makes any emotional approach by you more valuable/powerful.
