The E.M.I.L.Y. System

Chances are you've blown it with your share of potential suitors.  Wouldn't it be nice if there was a treasure map of sorts to lead you from "Hey, I'm a nice, innocent guy who needs a beer pong partner and you caught my eye earlier," to "Hey, I'm a nice, innocent guy and I'm taking you home to my parents' house for Thanksgiving this year because I want them to meet my new and very favoritest girlfriend"?
You're in luck.  Go with the foolproof, easy (and fun!) to use E.M.I.L.Y. System:

Exposing secrets:  Relationships are built on a solid foundation of honesty and trust.  So divulge everything, preferably on the first date, if not sooner.  Tales of boyfriends past, your struggle with meth addiction, the time you got chlamydia after a run-of-the-mill gang-bang; it's all fair game.  He's going to find out eventually, right?  "Remaining mysterious" is an antiquated practice; this is the era of Facebook and Twitter and sharing EVERYTHING.  He'll respect your openness SO MUCH MORE if you tell him about the time you got dumped for getting thrown out of Lollapalooza after you *ever-so-innocently* punched a girl in the face because she asked your then-boyfriend if he was "In line for the bathroom" (stupid slut) in the beginning instead of getting to know each other first.
Mass texting:  Duh.  What else are relationships built on besides honesty and trust?  Communication, of course.  So keep it up on your end.  Don't. Stop. Texting. Ever.  Even when you can't think of anything to say, even when you have nothing to say, and especially when he tells you in advance that he'll be busy.  Guys absolutely love being digitally stalked.  If you've gone over your monthly limit on texts, e-mail him.  Write on his Facebook wall.  This step is exceptionally effective if performed when you are intoxicated late at night.  Nothing says, "I'm normal, date me" like 14 incoherent (and unanswered) text messages and 3 e-mails asking your new beau about his sister's wedding, telling him how much you miss him, and subsequently berating him for not being kind and considerate enough to reply to you at 4:30am on a Tuesday.
Insanely apologize:  Ooops. He ended up getting a little peeved about your influx of "communication".  So apologize.  Beg for forgiveness, attempt to elicit sympathy by blaming extenuating circumstances for your behavior "my cat died, I put a red sock in with my whites, AND I cut my knee while shaving... ", and tell him how much of a connection you felt even though it's only been two weeks.  Guys will respect you so much more if you don't respect yourself, so get down on your hands and knees, and beseech him not to "walk out on you like everyone else always does". 
Lead with your vagina:  He may not be buying the bit about your dead cat (shouldn't have posted that photo of Blinky taking his first bath 2 days after he supposedly perished in a freak accident involving a Glade air freshener and your sinister roommate).  So lower yourself down a few more levels.  Waggling your vagina at this dude is a surefire way to win back his affection, respect, and admiration. Send him some dirty yet tasteful photos with captions like, "C'mon, baby, don't you at least wanna come fuck me?" or "I can't go on living without sucking your big dick at least once more."  Trust me.  It won't make him start using you primarily for sex after he's been out with his boys and couldn't find anyone else to take home.  So harness that indomitable sexual power you know you possess deep inside you and reel that boy back in.  Your relationship will be back to normal in no time at all - probably better than ever!
Yeah ... he gone:  Oh, wait.  Wait just a second here.  This guy has already realized that you are a schizoid whore with no self-respect, and, according to too many of your "getting-to-know-me" stories, a drinking problem, an angry streak, and a propensity for late-night binge eating.  He's had one foot out the door for awhile.  After using you as an all-else-failed, last-option, go-to glory hole a few times, he'll move on.
