I was in an abusive relationship for 6 years and now when I date people I find myself pushing them. Deliberately disagreeing to see how they would react. Maybe she is just trying to feel secure but she's achieving nothing, if you would do those things you are highly unlikely to admit to it.
Tell her how you feel about her asking you these question. There's only so long you can put up with lack of trust. It takes a long time to get over an abusive relationship, in my opinion, and she has the added bonus of the next relationship being an utter disaster area.
If she is always talking about what happened to her, chances are she just isn't over it. Personally I wasnt ready to date for 2 years after it finished, I did but I did everything as destructively as I could muster. She may also be doing this, just in a different way, hence the ridiculous questions.
