Mother looked through twitter account and found some things...?

[poooooof]

She found some nasty things i said about her and my dad. She confronted me today and now i feel REALLY guilty about it. But i believe that it's wrongdoing on her part too. Because my parents have been invading my privacy since young, checking my phone messages, reading my diary, stalking my facebook account, reading my blog, and now my twitter account, and i have nowhere and nobody else to tell my problems/vent my anger to. And the worst part is she always tells all my relatives about this. So today she scolded me and said that i shouldn't announce my family problems to the world. But that's what she does, to my relatives. And the reason why i posted mean things about them is because my father YELLS at me for every single stupid minor thing i do that he does too and i can't say anything back despite how right i am so i have to stop myself from saying anything back or he'll call it talking back. And since i can't say anything to him i vent my anger by posting about it on twitter. But i don't understand, how did she manage to see my tweets? My tweets are protected. She must have checkedit from her iphone because i logged in from there before. So i'd like to ask 3 questions:

1. whose fault is it? Mine for saying mean things about my parents, or my mother because she invaded my privacy and read my tweets?
2. How do you sign out a twitter account logged into an iphone using another ipod/computer?
3. Is my mother going too far invading my privacy? And if she is how can i stop it.

Thanks

Let her know that what you said was in private and was meant to remain in private and is a non-issue. Let her know that she violated your trust and that it would be very difficult to trust her again. Let her know that she is setting a very poor example by violating trust.
