WIBTA for exposing my friend being a side chick?
So my friend D has become a side piece to one of her coworkers, he has been saying for a year that he will leave his current girlfriend, but he still hasn’t. Me and N both wanna tell the girlfriend because D is too much in love to stop this herself, but so far we have only sent the girlfriend a text anonymously on a fake account N made
Any advice on what we do from here?
