My bff accused me...

Is it normal for her to do this ?
Let's start like this: I introduce her to a guy in fb( me & him are good friends), she fell for him. He didn't say that he felt the same for her, so he just kept talking to her. After that he fought with her because she broke a promise, and he blocked her and blah blah... One day he said that it was his last day in fb, so he wanted to say a good bye to me, I didn't believe him, and she was insisting to know what he was telling me. So I was sending her his messages because I'm her BFF. Then he published in my wall a song of James Blunt(Goodbye My Lover). She saw it and asked me what's wrong with him, I told her as a joke; he must be crying because we are going to separate. Then she said Please stop,don't tell me what he is telling you because that's hurt, really (My Lover)!, I said what's wrong she said JUST ADMIT THAT YOU LOVE HIM, BECAUSE YOU ARE TALKING ABOUT HIM(like WTF she is the one who asked for his messages). I told her if I did u will be the first one who should know. she couldn't stop yelling at me and saying u hide it from me that you love him -_-. When I saw her mad I didn't want to talk about it, she said and now u don't want to talk about his subject so that prove it.
She only wants me to say yes I love him, so she can blame it all on me.
The thing that hurts me that she didn't trust me, and she thought that I would hide something from her.
Since she met that guy she forget all our friendship. She fought for a guy whom she met only in 6months and forget that i was always there for her more than 6years.
So is it normal and what do you think ?
