Hopefully someone can help me out! My boyfriend and I have recently spilt up, and he was using my iTunes account on his iPhone to download apps because he didn't have a credit card. He is still using it, and I can tell because I can see all the apps he downloads because they are downloaded on my phone. How would I go about disabling him from using my iTunes account? And also, I had a little panic attack when I heard people who share iTunes accounts, one person can see the others iMessages. Is this true as well? Thanks for your help.
