You don’t like your fiance’s old college drinking buddy and are worried the he’ll ask him to be his best man.
In this case, the decision is not yours to make. Best friends are almost like family. How would you feel if your fiance didn’t want your best friend to be your main of honor? For the sake of your marriage, try to learn how to appreciate his closest pal. After all this person has probably been a part of your grooms life for a long time – and likely is going to continue to be. If you still want to persuade your groom not to ask him to be part of the wedding party, discuss other ways of including his friend, such as asking him to do a reading – of your choice of course – at the ceremony.
