Unless you are finally able to see the violations your enemy commits upon you from a more expanded perspective, you will not be able to free yourself enough to experience abiding happiness. Your projections upon him/her, true in fact or not, will only rebound back upon you.
On the other hand if you let go of your enemy, freeing him/her from the prison of your projections will set yourself free from rebound, opening the gates of freedom and joy to you. Therefore, gather what remains of your material and spiritual goods, and walk away.
