Here are a few of them;
A gossip art is the kind of friend who you feel like you can tell everything to. These people have a certain likable secret-ness to them. Sadly they tend to spill your beans a little to much. For example; "Remember that time you puked on your teacher?! Ha yeah and then your crush wouldn't look you in the eye for the rest of the year. Yeah that was funny." - Friend "Oh my gosh, is that for real! Wait let me tell Alex and Sierra." - Random Person. Yeah i know what a backstabber.
Your friend may not be the right person to open up to even if its hard not to.
Don't worry your friendship may not be in danger, even if you may have some fights. Try not to always trust them... Like maybe lay off the stories that you want to stay a secret. You can still be close friends but maybe don't tell her about the time you mad out with a hotdog.
The disinterested friends can be the worst. Sadly these friends love to ignore you. They seem to not be as into the relationship as you are. Maybe they can't come out to your party because they have to be at the "movies". Yeah that can sting
Your friend may not need you as much as you need them. Sadly it's there fault.
You might need to re-think trying to hang out with your friend. They might have moved on, and as much as it pains me to say this; You gotta deal with it. Here's a saying; When life gives you lemons, squeeze then in mean peoples eyes. So yeah squeeze away.
This friend of yours may not have the time or the mind. You are waiting in a very long line for a movie you were dying to watch with your friend, but then you get a call/text saying she/he will be late. Shit what are you going to do? You wait a little bit longer to find that she/he actually can't come even though you planed this event months ago. Later after watching the movie alone you notice that your friend has posted pictures of her/him hanging out with some other friends. Wow that hurts.
Your friend ain't got time for you and that sucks. This friend also isn't very good at hiding there tracks. Even worsetey don't really care if you crash and burn.
Cry, eat icecream, chat to your mom/dad/someone easy to talk to, Read lots of books, ignore them, disfriend them,move on.
So i hope you learned a little more about some bad friends to have
