I am not on speaking terms with my sister, her choice not mine. It's been several years since we last spoke. She basically told me off and said she wanted nothing to do with me ever again. Without getting into all the details, her attack on me was unwarranted. She's done this before and even though the ball wasn't in my court I would be the one to reach out, again. Anyway, her son is now getting married and I received an invite. Not sure how to handle this. I was very close to my nephew when he was growing up and have stayed in contact. What would you do? I would like to support my nephew and his bride by attending but I also respect that this is a special day for his mom too.
