confused.

i dont understand why this always happens to me. am i the only girl in the world who cant make up her mind? why do i always give up something thats good for something i believe is going to be better? i wish i could just redo high school. and by that i mean my dating life. first mistake: dont date someone for basically your entire four years. date different people to figure out what you want. because once you get into that first relationship deep, its hard to get out of. i have never been one of those girls that dated a bunch of people, always one of those long term relationship people. and i dont know why. and break ups suck. they have to be so much easier if you dont get attached. unfortunately, ill never know. anyone out there know what im saying?
