...nice avi, btw...

I would be concerned about a noncommunicative partner- in any relationship... perhaps other venues than speaking may be easier for her? Writing in a journal, writing you a letter, writing a story, posting here, even maybe chatting with others might bring her feelings and desires out.

I would not doubt myself so quickly if I were you. If you are simply looking for play ideas, there are many stories in the library that may spark something (just remember where the line between fantasy and reality is- some things must be left in stories). And there are many websites and books as well.
