Input: This was awhile ago. I was a bit drunk and I told somebody that I wasn’t that close with that their girlfriend was cheating on them. This girl I was close with told me on multiple occasions how this girl cheated on her boyfriend. They were in a serious relationship for a couple years and would tell each other they loved each other. One could argue it wasn’t my place to tell him but I just felt like he really needed to know.  She denied it but I I think he had his suspicions before I said anything. However they are still together. Am I the asshole? I feel like I am 

Edit: as soon as I hit post I saw my grammar mistake. 

telling somebody there girlfriend is cheating on them
