She has already given you her hint.
Ever heard the saying that a girl knows within the first few minutes if she is going to have sex with you or not?
This is the case. She doesnt want anything more from you, including a relationship - and she has attempted to make this very clear with you.
she didnt want a relationship but wanted to "get with me"(i dont feel like im being used) i asked her why she didnt wanna make somthing more between us and she told me its because she always manages to f**k relationships up.
You were used. Enjoy the one of few times in your life that it will ever happen.
anyway i wanna know how i can change her mind,should i ask again later on or take some action
You wont be able to change her mind.
One of the biggest problems that timid / shy / inexperienced people have, is that when they finally do meet someone, regardless of who it is, they immediately get this feeling like "Something is there" - when it never is. It could be the girl next door who says hello, the lady at the grocery store...etc. Any woman that comes into their life, they think "something is there".
You need to move on, and find a different girl. Any woman that you have known for over 3 years, friends with for over a year, and finally had one single encounter that never escalated, is not someone who wants to be with you. If she wanted a relationship with you, she would have said so, rather than saying specifically that she did not.
Just move on. There are a million other "fish in the sea". If you were to somehow actually get into a relationship with this broad, it would fizzle. Why? You guys don't have passion for one another. Once she specifies the boundries of your relationship, that is all it is ever going to be.
