My best friend cheated on her boyfriend and blamed me?

Anonymous

I love my best friend. She's great in so many ways. But something happened recently. Her and her boyfriend were "on a break" when she came up to visit me at uni. Their break-up was only temporary, and she wanted to look for guys that might interest her at my uni, so I introduced her to this guy. She ended up hooking up with him and slept with him.

She then called her boyfriend crying because she slept with another guy on their break and he 'officially' dumped her. After that, she didn't talk to me as much and I found out that she told him I encouraged her to hook up with the other guy and she's not at fault. And now her boyfriend, who I was friends with, hates me. He has taken her back but blocked me on everything and she has been not answering my texts.

What should I do?

I know I shouldn't have set them up but she was interested in this guy and I introduced her. Am I in the wrong?
