Sometimes it takes longer to heal from something like that. Give yourself some time.
Maybe because you want to save the relationship?
Are you ready to let the friendship go? Letting go will help ease your pain, but are you, perhaps, holding on,hoping to reconcile? Only you, and your friend, can decide if that is possible. If it absolutely is not, if it will never happen, no matter what, then you need to learn to let go, otherwise you are inflicting pain on yourself for no good reason, and to no good end.
