Should I write her?

So about a week ago me and my girlfriend broke up after 6 months. She said she wasnt in love with me anymore. I gotta be honest, I miss her more than anything else right now. I want nothing else than to be with her right now. She said some things that confused me when we broke it off. I said I was sorry we were gonna break up, and she said "Me too". What does that mean? That she wanna be in love with me, but isnt? Or am I putting to much into that? I really really wanna write to her to tell her how much I miss her. I know it might be a dumb question, but I'm gonna ask anyways. Should I write her?

Write the letter, but do not send it. Keep it for 30 days, and if you still feel like sending it, send it. I bet you won't.
