Dear Prudence,
When my wife was a teenager, her older brother died very suddenly. I hadn’t met her yet when it happened, but I know it was very traumatic for her and her family. Before his death, her brother had been engaged to “Jane,” who had been close to my wife’s family but who fell out of contact over the years. Recently, we found out that Jane is getting married to “Joe,” who happens to be friends with my sister’s boyfriend. The wedding is being held at a popular vacation destination, and my sister and her boyfriend will be attending.
Jane’s wedding has kicked up some grief for my wife and her parents; my wife has admitted that she keeps thinking about the wedding her brother never got to have, and she tears up or withdraws whenever someone talks about it.
The problem is: My sister keeps bringing it up in every single conversation we have with her. I understand that some of it is excitement for an upcoming trip, but it’s every. single. conversation, at length, no matter what we’re talking about. I explained the situation to her and asked if she could hold off on talking about it with my wife, but now whenever she brings it up, she just prefaces it by saying “I know [my name] says I’m not supposed to talk about Joe’s wedding, BUT …” I’d prefer to just avoid her until she eases off of this, but my dad has health issues, and my wife, my sister, and I see each other regularly in the course of taking care of him. The wedding is months away. Is there anything else I can do to handle this?
