Sometimes we just have to let them go, it's still a DB strategy. If what you are doing, that being trying to remain friends, is not working then stop doing it and do something different. We all get trapped into repeating strategies that we believe SHOULD make a difference even when we find they don't! Give her space, live your life and, as RMG says, close the door but don't lock it. You never really know what's around the next corner, it could even be something good!
