If you will continue to see your old pal regularly, try to be civil. Make a commitment to be the bigger person when the two of you make contact. Remind yourself that you once cared for this person a great deal (and probably still do). At least pay homage to that relationship by being cordial when you two interact.  Having an ugly confrontation or badmouthing your ex-bestie won’t help you get over things. Even if there’s bad blood between you, stay cool and avoid trying to make your mutual friend
