Does anyone have experience with Dissociative Identity Disorder, specifically dating?

I've started to date a lovely woman, and she's now allowed me to know that she has Dissociative Identity Disorder. I've done my best to read and watch information about the 'disorder' but I was wondering if anyone has had any experiences that might they're willing to share.

I know that everyone is different, and there's no set way anyone who has it acts or behaves.
