I'll be honest. Every last word you write makes me think you're a bad person to date, and maybe just a bad person in general. You think being clingy is a good idea. You're intrigued by playing hard to get. And you think that all sorts of people love you.
This paints a clear picture of a very immature, very self-centered woman that is on a dangerous path towards being a poisonous friend and girlfriend in the years to come. Hopefully, this system of beliefs you have is just a result of you being young and ignorant of how people like to be treated. I'm going to work under that assumption, because that means that you can be helped. And I'm going to help you.
Being clingy is not a good thing. Being clingy means that you constantly need attention and validation. Guys don't like clingy, because clingy means they need to babysit you or else you'll get cranky. Instead of "clingy," try "compassionate" or "interested." You should want someone to spend time with you because they like you and you like them. Make people want to be with you by being interesting, funny, and charming, not because you're a clingy child that would have a tantrum otherwise.
Playing hard to get is also not a good thing. Is it fun? Perhaps, but it is also sadistic. The thrill of the chase is fun for the person being chased, but the person doing the chasing can be made to feel inadequate and hurt. If you like a guy and he likes you, it's fine if you start dating. You don't need to run someone through the gauntlet first. That's what cruel people do, and I hope you don't become (or remain) cruel.
I sincerely hope that you are a better person than your question led me to believe. And I also hope that you can change your behavior. If you keep acting the way you are now, you're going to be lonely, and all those around you will see you as a manipulative and petulant child.
Ladies, what are your thoughts on this? Does she need a drama intervention?
