Seriously nothing in the entire world makes me more upset than this. Not happy? BREAK UP! Or, be in an open relationship or a poly relationship. If you cheat on your significant other, I don't want to be your friend. It's not "complicated". You are a selfish ass. We are done.
2. Choosing a guy over a friend
If we are friends and I show you the creepy texts your boyfriend sends me at 2am asking me if I sleep naked and you choose to stay with him and won't talk to me anymore. And then you start sending me messages after you guys break up all like, "Oh hey friend!". Ummmm no. Our friendship is over.
3. If we are friends and I find out you are talking shit about me to other people. I won't be texting you back EVER. Don't expect an angry email from me explaining either. You aren't even worth it.
