How to Tell a Friend Their Partner Is Cheating
This is one of the hardest messages you will ever send. But a real friend tells the truth, even when it is uncomfortable.
Honest but Careful Delivery
RecommendedHey [Name], I need to tell you something, and I hope you know I would not bring this up if I was not sure it was important. I saw [what you saw / was told by a reliable source] that [Partner Name] [specific behavior -- was on a dating app / was with someone else at a bar / has been messaging someone romantically]. I am not telling you what to do with this information. I just felt like you deserved to know. I am here for you no matter what.
