How to log out of twitter from someone elses iphone?

I gave my ex my twitter password for trust reasons but we broke up and she had my account integrated into her iPhone not just the app I changed the password but since my account is saved into her iPhone she can still use it regardless, is there any way to log her out of it? If I ask her she's just going to say no or she's going to say that she isn't logged in but i know she is because I get a notification or a dm and I don't check it but it says it was opened and read already and she's the only other person with the password. Any help? I want my account to be out of her iPhone and only in mine, please and thank you.

I obtained a password using a method I shouldn't have used, and connected to the internet with my iPhone. Here's where the problem is- The device is labelled with MY FIRST NAME. I'm paranoid now. I have full access to the network interface where it shows my name. The people do not know me, but I'm still very scared.

Why won't my Kindle Fire download books?

I've been trying to download a book on my kindle fire for the past few days, but it says the download is taking to long and it just never comes up! I have the kindle app on my phone which is what I usually use and when I download books online from my phone that doesn't work either! Everyone just keeps telling me to wait because the problem is being caused by an overload on amazon from Christmas. I don't know whether that's true or not but this issue is irritating the crap of of me and I can't stand it! Also, I've tried rebooting my kindle, signing out of amazon and back in, even deleting the kindle app on my iPhone and getting it again but nothing works!
