I. Tell her you need to talk. Look her in the eyes, and tell her everything you've always wanted to tell her. Tell her all your thoughts - the good ones, the bad ones, the nasty ones, the irrelevant ones. Find a way to make the nasty ones less nasty.
II. Unfollow her on social media, and defriend her on Facebook. Delete her number and all those pictures you took of her because you didn't want to forget. Forget. It's okay to cry over her.
III. Change your favorite color from gold with olive specs (like her eyes) to just gold (like sunsets; like it was before you met her). Colors shouldn't be all about her anymore. They never should've been. You can cry about her.
IV. Don't let the memories of her make you bitter. Don't drive past her house. Don't look for her on the street. Delete the playlist you complied with songs about her. If you see her, wish her the best but not to her. You can cry about her.
V. Don't regret leaving her. Don't resent yourself for listening to her when she told you to leave; don't ask her to take you back. You can cry about her.
VI. Pray she'll stop coming to you in your dreams and nightmares. Know she doesn't really miss you. She said it herself: she's happier now. Wish her the best. You can cry about her.
VII. When people ask about her, speak of her how you would speak about someone who passed away. Only speak of her with love in your voice; speak of her how you did when you were in love with her.
VIII. Realize you are no longer in love with her. You can cry about that.
IX. Don't ever go back to her. Don't live in the memories. Don't cry about her anymore. Drink your favorite tea again because you like it a hell of a lot more than her favorite. Wear the perfume you have that smells like hers. Pretend the comfort of her exists without her.
X. Repeat as necessary.
