Be really good to him/her. Let the person feels guilty...

Go and talk to him/her!!

i think you should confront her/him in a diplomacy conversation and tell you hurt that rude manner then give a second chance because i believe that second chance is always a chance. Thanks and God bless you....

I guess they won't be your friend anymore . Will you ever be able to trust this person again?

Talk to my friend. Ask him/her why they feel our friendship must be worth so little to them that they could hurt me like that. Friends should be there for you.
