crying out loud!

I just stopped being friends with someone who used to be one of my best friends! I do not know why did I take took him off my friends list, but I felt that I needed to, maybe because we already know each other too much/well/intimately/closely - what to do with all the memories we made/of the things we did together? I just wish that every time he remembers/recalls/thinks of me, he smiles - but or maybe he will hate me. We know too much about(?) each other, too much but he isn't honest with me. We both know it. <em>(hard to tell what the sense of know too much might be)</em>
