you don't know good until you've done bad. you don't know how you should be treated until you've been mistreated. you don't know love until you've experienced hate. you don't know a bad guy until you've been with a good one.
and i for one, am glad.
i'm glad i waited to get serious with someone until i took myself seriously. i'm glad i dated a bunch of assholes so that i could recognize a good guy when he came around. i'm glad i have the man i am with today.
