My boyfriend and I are friends with this couple. I was friends with boyfriend before I became friends with the girlfriend. My boyfriend and her boyfriend are super close friends. Last night he went to a friends house to fix something on a car. He told his girlfriend he was going to a guys house and he told my boyfriend it was some chicks house. He then went to the casino and didn’t come home till noon today. She was on her music app that they share and he listened to a “sexy” playlist recently. She was freaking out and venting to me all day about how she thinks she cheated on him. Should I tell her that he went to a girls house? I feel like I should because I would want to know but I feel like I shouldn’t because I don’t want to cause drama between us and the boyfriend. Help!!!
