Be thankful to your enemies, because it's their wrongdoings to you that makes you smarter and wise. It's because of their bad karma that you become the better version of yourself. You don't have to forgive and mustn't forget, but just have to say "Thank You" and move on with life. Move on with Life, because life is too short to be wasted, even a single moment, on such undeserving and illegitimate folks.
