Ugh I hate complications... yesterday in class the guy I like, landon(not real name) and our friend tommy (again, not real name) were talking about a girl on their bus. As I was listening and talking with them, tommy accidentally said her name Baliey (not real name still) and I said Baliey? Then I said her last name and tommy was like crap, yeah her. I told Landon that I wouldn't tell her and I'm going to keep my promise.
I was talking to her today and she told me that he liked her. But she said she didn't like him. What am I supposed to do with this info? Should I tell Landon that she doesn't like him, which would probably hurt him really bad. Then he would think I broke my promise. Or should I just leave it alone and still "talk" to him and just hope he changes his mind about her. I really needsome help here...

Just stay quite and let things work out the way they do
