Dear ex,
I thought you were the one. The connection that we have shared since our very first date still exists, but it's different now. I hope someday you realize just how much you mean to me and I to you, but until then good luck finding happiness. Did all of our time together mean nothing to you? I hope you remember all of the memories we made together. If I was so wonderful and caring, why did this have to end? I miss my best friend. Take care of yourself.
