I just got out of a relationship that ended very badly. I want to forget about all of it, even her. I want it to be like she never existed to me. I know all about the moral dilemma as I have been a practicing Wiccan for the past 10 years. This is only for me. She will have no idea about it and she will still have the memories of it all.

Does anyone have any ideas on how to go about doing this?
