Get rid of any communication with her, even through acquaintances. You will find nothing but pain in it.

Remove all her belongings from the house, pass the leftovers through friends, or send by courier.

Don't listen to any more music related to her. This includes movies, books, familiar cafes, clubs, etc.

Don't answer her texts or calls. This is a trap.
