How to forget about someone important
Make a relationship log.
If you're trying to, a good way to start is logging the relationship. Recording your feelings about the relationship as honestly as possible can help you understand why it ended in a more objective sense.
If you lost someone due to death, logging the relationship can allow you to grieve and feel a sense of closure. Regarding a broken romantic relationship or a relationship with a friend or family member that fell apart, try and be as objective as possible when recording your relationship.
