I start shit consistently, but you are clearly a drama queen. I don't see why you calling me one means you aren't.
Also, with my roommate, he stole my shit, I regulated, and the problem was solved. He paid for everything that he had to and never tried a stunt like that again. That's not drama, that's how shit is handled. You could use a lesson on that. Handle shit, don't fucking whine and then retreat to a bottle of booze and whine about your problem on facebook, thinking that it will be some sort of revenge. Its not, its just feeding into the drama that you secretely love.
Also, you didn't just embarass her, you embarassed yourself. Once you come out of that weird drama-obsessed period of that relationship you will realize that starting a public argument just to make your girlfriend look bad makes you look like more of an ass than her. Ironically, usually this is something you have to explain to extremely drunk young women, the most dramatic people in the world. Don't forget, YOU started the argument, not her.
