Ugh, Kenn, I'm sorry. That sounds like a very sucky conversation. MsM is right, very un-DB but hopefully you feel better getting it off your chest.
It's obvious she is pushing your buttons and you're giving her the reaction she wants. I would strongly recommend that you go as dark as possible and speak only about things relating to D or business matters.
Remember the old adage: if you can't say something nice, don't say anything at all.
By refusing to engage with her you are shifting the dynamic. Hopefully it will take you out of her crosshairs and she will be left to examine her own actions. And even if that doesn't happen you'll have some time and space for yourself.
If you love somebody, set them free. http://tinyurl.com/2empx2g
