I broke up with my ex a little over a year ago. We’ve both dated other people since. I recently got word that she’s now dating my boss who was also kind of a friend outside of work. Because I know him, he is well known to try to hook up with his friends leftovers. It’s strange. Anyways, when she dated others I didn’t care, but for some reason I’ve found myself taking this particular situation kind of hard. Given how long ago the break up has been, how would you feel if this happened to you? Would you be upset or should this be water under the bridge?
