Thinking about all this just makes Unreal feel tired. And sad. And, unfortunately, it gave us a raging case of insomnia. At 2 a.m. we conceived our own brilliant theory, which will, of course, need to be scientifically proven, so we may start wandering around the Delmar Loop with clipboards asking people if they've got a minute for male-female romantic relations.
Unreal's theory is this: Women poach because men allow themselves to be poached, and the ex-girlfriends get mad because they all adhere to some unspoken rule that men are so important that straight women have nothing better to think about or fight for.
