Not understanding my partners actions.

I am a Aspergers and ADD sufferer but my girlfriend is an NT. we have been together for over 3 years but since my diagnosis 8/9 months ago it seems a lot builds up and then we struggle to solve very simple issues.

all along she has told me that she loves me and wants us to be together but recently all of a sudden asks for space and can't talk to me. always without warning or any kind explanation so then I just have to sit and wait for her to return.

because we were together when I was diagnosed we have been studying and learning about it together. and know we know these things she says that these breaks aren't driven by the fact that I am a sufferer.

please help!!
