<human>: Provide a brief overview of the text.

We've been friends for a while but she still feels like she knows nothing about me. In a way I understand this because I've always been a rather reserved person and not very good with talking about myself. 

However, I've told her to feel free to ask me things whenever she wants yet she rarely does claiming she doesn't know what to ask and she just wants to know everything. She also mentioned being a bit embarrassed about asking about things I might not like (hobbies, interests, etc. I'm assuming due to context)

Any advice on how to make her feel more at ease with asking me questions. Also, how can I improve on talking about myself and letting people get to know me better without waiting for them to ask? What sort of things constitute "everything".
<bot>: GF says she doesn't know much about me, won't ask questions/feels embarrassed to ask. I'm not sure how to work on this.
