..."this relationship is going nowhere".
yanno, its nothing your doing, or not doing...its her, I think today, most people indulge in a physical relationship before they know who they both are, if they share some common ground.
She has most likely decided that the both of you do not have much in common, or, perhaps she feels like you deserve better, b/c she knows herself better then anyone, and views you as a guy who fell in love with lust perhaps.
I wouldn't play games, cause that can always get you in trouble...but I would back off, give her space and allow her. Love is also hard as it may seem, understanding that what once was, isn't a life time thing...and she needs to grow. When someone says, if its meant to be it will be, listen to that, and don't force it. Go with the flow, chalk it up to an education and be happy for her, and for the fact that you've found out now.
Funny, but people today, upon endulging in an intimate relationship forget about the human heart...and that's sad. It's all about instant gratification.
My best to you...and please, no matter what you do, always, always keep in mind, if you can, the heart of another before you act or react.
Maybe its time to walk in another direction and experience life in a way that pleases you. If there are problems in the beginning, the problems could and will escollate...so it's best to shake hands and go forward, in a silent sort of way.
relationships take time and hard work...and regardless of what society preaches, you don't "have" to be a couple to be successful. If you learn to really and truly love and trust yourself, your needs will change, you will grow wiser and less needy...and no longer need approval from others to be happy. Knowing oneself is like meeting a best life long friend
