LV, if you leave your love hovering around her, what happens in her life -- which is not formed with your feelings or well-being in mind, whatsoever -- will continue to negatively affect you. Collect back your love and love yourself, for now. Learn from what transpired, and have faith that your real love is wading closer, with every day this woman disappears into the old horizon.
We all go through the hurt of getting our hearts trampled on. I have, you have, everyone will, if they're trying at all. In the end, we understand that the tragedy was good and right, and worth going through.
Again, you may understand in time.
