Wow. You forgave your best friend. It definitely takes a lot for a person, any person being at that, to forgive a person that does them wrong.
Kudos to you for being the bigger person and forgiving your best friend.
Maybe you have to talk more with your partner about what happened at that party last week Friday.
Maybe they were the one that really did you wrong and not your best friend. Who knews?
Friendships can go through so much in any given period of time. But it is important to work through each problems and hope for the best!
The End.
