Hey [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.

Hey [Name], I know this must be really difficult to hear, and I am so sorry to be the one telling you.

Whatever you decide to do, I am in your corner. Always.
