Today’s open thread question is inspired by a comment from last weekend’s open thread. As we were all recalling our moments when we knew we found “the one” (or, one of the ones), someone asked about those moments when you become aware that he or she definitely isn’t the one. I bet we all have more than one of those moments, huh? So, please, share your stories of when you realized the person you were dating was not going to be the person you stayed with much longer. And, if you don’t feel like discussing that, tell us what you’re up to on this lovely May Day weekend.
