My friend (female/19) was involved with someone(male/21) and this person didn’t want their relationship to be known (only I knew) and by now they’ve broken up and I told a good friend of mine (who knows her too) that they were in a relationship (because it was about how that someone else is starting to date another friend of us) but I feel like I betrayed her trust by telling someone about it. What to do? Should I tell her he knows? Or it will only hurt her? And should I tell her that her ex started to date our friend?
TL:DR: I told a secret to a friend and I need advice
