My fiancé's daughter-in-law passed away suddenly 30 days before our wedding. Everyone is still in shock. Her husband is co-best man and one of her sons is the ring bearer. It's a second wedding for each of us and we're planning a small church service and restaurant reception with about 40 people. My fiancé wants to go ahead with the wedding since so many of our friends/family have made non-refundable travel plans. I'm heartbroken by this loss and am unsure what to do. Any advice appreciated...
