All and by all i mean like 95% of my friends all have boyfriends or girlfriends. I'm the only single person and i really really hate it. Not because i want a boyfriend or girlfriend or anything but because all they fucking do is talk about how they love each other. Or one of them chooses to be a bitch so a whole plan is cancelled and worst of all i have no one to go partying with because they are home with their boyfriends. What should i do? and is this normal?

You could learn from Barney Stinson.
