A girl called M told me a rumor about a friend of mine called A. I went and told S what M Said about A. After I told S i went and told A what M said and she blamed S for starting the rumor. After I told S I went to A to tell her, even though i promised S i wouldn't say anything to A. To be honest the only reason I told A, is because the rumor could destroy her relationship with her boyfriend. Now is S and A fighting about the rumor. When S asked me if i told A about it. I said no, and I let S believe that M told A cause M told me about the rumor. It's been a week now and S and A isn't talking to each other, and now I feel a little guilty for telling A about it.
