Right now, when new people make small talk, I say I moved here to be closer to my daughter’s family, since I’m single. But I actually disowned my son, “John,” when it was discovered that he was committing sex crimes against minors. I switched to my maiden name after the divorce, so unless someone’s really nosy, they’re not going to immediately find things about my past. I haven’t dated anyone seriously enough for it, but at some point, should I say something to close friends? There’s no guarantee that the vasectomy reversal will be successful, and it’s even less likely that you emotionally recover from this.
