Do you think she will hate me?

Okay, so I went to highschool about 2 months ago and I have some new friends. But I only close to the girl who sits next to me, her initial is R. She's close with this guy in class with initial Y who always bring an SLR camera for the last 2 days. She told me that she thinks that Y has some feelings for her. She also told me that she thinks she likes him too a little bit. What sounds a bit wrong to me here is that she already has a boyfriend and they'll go for their 1 year anniversary in a month. I wanna make this straight, so I asked Y through FB whether he actually likes R or not but he told me that he has no feeling for her and it was just a misunderstand. He asked me to tell that to R, but I refused because I really don't know how to say that. Beside, I don't want to hurt her feeling too. I was surprised because few minutes after it, R chatted me : "Gosh, what did you told him?", I explained everything to her. I didn't mean to provoke or something but I just want to know the truth and I think this will help so that she won't put big hopes on him and feel disappointed even more. I said sorry and she said it was okay. Do you think she'll hate me? I still feel horrible about it
