I miss her..

I'm trying really hard to ignore the fact that it isn't bothering me, that I literally don't think of her, that she probably hates me. but in reality I miss her so much, i miss how we often we used to talk late at night, i miss how i made fun of you and instead of getting mad you did the same, i miss how you posted my funny texts in your stories, i miss when u told me about your day, i miss how you used to vent to me, i miss how you told me literally everything to me, I miss when u said i was your bestfriend. I don't know what changed and suddenly im nothing to you. I told my friends about you and they told me to just move on. How do you just move on from someone who meant everything to you? I literally miss her so much but i have to act nonchalant....
