This relationship does sound pretty toxic. I think you crossed the line back when you gave up all your friends for her. That's just plain stupidity, if you ask me. Here's a question for you... do you know who she talks to on the internet and what they talk about? The only reason I ask is... if she is doing something over the internet that is wrong, and then you start spending a lot of time on the internet, she'll assume that you're doing the same thing she is doing. Maybe she feels a bit guilty! But no matter what, she needs to get over it. It's just a fucking website. My ex and I were both on here at the same time while we were together, and it never caused any rifts at all. You need to stop allowing her to control you.
