I had to deal with it too. Look; If they don’t accept you, Leave them. If they can’t accept, Then they probably never cared about you in the first place.
I’m sorry that happened! Friendship’s can suck at times. I’ve gone through my fair share of deteriorating relationships. It suck’s; But all things end eventually.
I’m glad you were able to vent your feeling’s out, There’s no need to be sorry!
