It sounds as though she is moving on!! Which is what you should do too!
It may be that you are trying hard to get her back and in-turn you are just pushing her away. Give her time, give her, her space. It may be that you are too accessible to her that you are not giving her a chance to miss you.
I suggest that you move on with your life, It won't be easy, meet other people, go out with your friends. She will notice that you are not around, see you with other people and then maybe she will realize that she does love and that she does want to be with you!! Try it, if its meant to be IT WILL BE!!!!
Do you know people in Hawaii?
do u think i may have pushed her away too much by now?
Well, maybe not! Like I said try avoiding her, don't talk to her, go out with others. This may trigger something in her.
Moving away will be very healthy for you! If you already have relatives and/or friends in Hawaii then the move won't be so difficult for you. But, if you have no one in Hawaii, it will be rather difficult for several months, but if you get out there and meet new people you will enjoy your time there!
This time away will do you some good and her too!
