If there’s anything I have learned from the web series Friends, it’s that even the closest of friendships can face conflict. At times, they get resolved pretty quickly and the fight turns into a thing of the past, but there are times when things go beyond repairable.
Even the original poster (OP) felt that her friendship with her bestie of 15 years was tainted after she didn’t invite her to her birthday party. On top of it, she didn’t even gift the woman on her birthday, as they did every year, intensifying the rift between them!
