Don't run away from her. Don't leave her behind. You know you can't ignore her forever. She will just keep hoping that you will come around and realize that you love her. Life is pain, if she isn't hurt by you then she will be hurt by the next guy. I think you do love her to some degree, or atleast care for her a lot because if you are this worried about hurting her you must care. Break it to her gently, remember that you care about her, let her know that, and tell her how you feel.

ye i do care about her , after all this time this years ,long time ago i didnt wanna start it cousei said i dont wanna hurt her ,now i did andi feel like the mistake i was running away from is finnaly came true ,now its either say it or die
