Chris, I agree with Joseph, I don't see anything you did or said wrong in that convo. I actually think you did quite well! You stood up to her, and when she kept trying to manipulate you into feeling like you are the one doing something wrong then you stood your ground and walked away rather than let it escalate into a fight. The right thing to do at this point is STOP CONTACT. Let her think about all that and throw her little temper tantrums by text, you've got better things to do than get drawn into it.
I also agree with Sandi, as soon as you left she got about the business of cleaning up that phone, LOL! "Sure you can see it in just sec..." (delete delete delete)
