Why would a so called BFF of 20+ years not apologize to their BFF for things they did wrong to them?
if you have been bff for over 20 years maybe they can't remember the last time they heard you apologize to them and figure it goes with the knowing and not the saying.
maybe they never learned how... it happens!
Maybe they feel like they have nothing to be sorry for. If an appology is what you want you need to let them know. If something they said or did hurt you be forward about it. Afterall they're not mind readers.
Maybe they don't think they did anything wrong!!
