We are in the midst of grieving over the death of my fiance's best man. He was honored to be asked and gratefully accepted only to find out a week later that he had cancer. He passed away two weeks ago and everyone is at such a loss. This man was quite an amazing person and left an immeasurable imprint on this world. My fiance is not sure if he should ask someone else to fill that spot on the wedding day or if he should leave it open out of respect for our departed friend. Has anyone else out there been in this situation? Any advice on etiquette is welcome. Thank you!
