It sounds like you really need to back off and give her some space seriously. The more you try to get her to like you the more she will reject you no matter how much it seems like she might be interested or how close you seem you need to give her space. Like jello the harder you squeeze the more it breaks apart and goes through your fingers. It might even be too late at this point to salvage what you had since you kept on pressing issue. But its not all hopeless you learned a valuable leason hopefully. Maybe if you can swallow your feelings you can still have a good friend. Which isn't so bad trust me relationships aren't all that great especially realtionships with an indesisive lying to your face so she doesn't make you feel bad type. Good luck i know the feelings that you have now suck but they will fade with time. I have similar experiences with girls its best to just move on. Sorry if it sounds harsh.
