I found out through a mutual friend that a good friend of mine might have been cheated on. They made it sound like it was multiple times casually. The mutual friend that I heard from can be quite scatty and get information wrong and I have no idea for myself if it's true or not.
Do I tell my friend what I've heard or do I keep it to myself/ignore it? If I knew for sure I'd definitely tell her but I don't know for sure. I don't want to cause a load of trouble for something that might just turn out to be gossip. What would you do?
