On and off friends..

Okay, so I have this friend who I am really close to.. we went to high school together (shout out to Northland!! whoot whoot lol) and we been close since freshman year.. We always would fall out or stop talking over dumb stuff.. but when we cool we are COO!! like I love her to death!! and at times I feel like the fallin out only makes up closer cause when we get back talking again we be right back to how things used to be (that sound kinda ghey lol but I digress) , my question is.. am I the only one who has a relationship with a friend like that? and does that make us fake for always falling out and getting back coo even though we dont talk about each other behind each others back when we not cool...?
