hi David..

when you say ostracize, do you mean physically and emotionally both? that would require banishing her from memory in all forms... wouldnt you still meet people who reminded you of her? you'd need to be able to eradicate all traces of negative emotion connected to her memory in order to cleanse yourself of her forever....

in removing the enemy from ones' own life, it seems best to first attack the enemy within...

seek peace within and it will appear without...

best wishes to you always
