Am I bad friend if I am straight forward and don't take shit from my friend.

My childhood friends don't get me even if they are wrong they just argue when i state facts and make me feel bad. We get into serious fight often and won't talk to eachother for months it happens with all of us in that group... They always be nice on face but do a lot bitching when that person is not there they pretend to be nice but I know thier real face... It feels toxic now I just told them that I don't want to be part of that group and I won't even call them even if I need them the most, I left crying they tried to show that they care but I know they are just better off without me. They never called or anything should I just end it.
