4. You Know Way Too Much About Sheila, at Work
"So Sheila, at work, is having this really awful thing with her ex," he says, a little too sympathetically. You nod, also sympathetically, because you know that Sheila has been having digestive problems and had to go gluten-free, and also that Sheila's aunt with whom she was really close died last month, and...hold on. Why do you know so much about Sheila At Work? An overly enthusiastic friendship with a so-called work wife may not translate to actual nookie in the actual conference room—after all, you don't mind him having female friends—but it could suggest that something is lacking from your relationship that he is looking for somewhere else. And he may not even know it himself. But when he seems to have more sympathy for the ongoing sagas of Sheila At Work than he does with your own various ordeals, that's more than being a concerned colleague. That's a "We need to talk" memo.
