How to hate a person you loved a lot
Delete the person's contact info.
If this person will no longer be part of your life, you should delete their contact information. This might help prevent you from calling, texting or emailing them.
You might remember their phone number or their email address, but removing them from your phone, computer, tablet, address book etc. Can make it at least a little bit more difficult for you to quickly contact them.
