How to get someone out of your head
Accept that the relationship has ended.
You can't move on until you've accepted that you and your former partner are no longer together and that the relationship isn't coming back.
Cut off communication.
Don't call, text, email, or otherwise contact or talk to your ex. It will only make it harder for you to get yourself together and move on.
