answer:You don’t. You can’t convince someone else to feel something they do not. Perhaps you should be less available? Maybe not hang out around her. Maybe look at other women as possibles. The benefits of this are two-fold. One, there is a remote chance she might miss you if you give her time and space to, and realize she does care for you. Two, you might actually find you can move on, which is what you really need to do. Hanging around loving her when she does not return your feelings is wallowing in pain. By the way, you are sure she does not return your feelings; you just don’t want to face that.
