A year ago my fiance's father passed away after fighting a battle with cancer. His mother quickly began to date again and has become very close with another man. My fiance disagrees with her choice to date so soon and move on from his father so quickly. I am fearful that when our wedding rolls around his mother will want her new boyfriend and perhaps his young son to be present at our wedding.This will devestate my fiance and I fear that it will ruin his day to look out and see his mother with another man. I don't want this to ruin the day for him and I, so would it be ok to request that she not invite him to the wedding? What should we do.
