You need a rebound.
You need one last conversation with them in order to receive closure.
You need to practice self-love.
You need to cut them out of your life permanently.
You need some time alone to rediscover what you want from this world.
You need to rant to someone close who will listen.
You need to delete them from your phone.
You need to pick up a new hobby or reconnect with some old friends.
You need to masturbate.
You need to block them on every single form of social media.
You need to forgive them — or forgive yourself — for everything that happened.
You need to practice self-care.
