Dreaming of exlover/friend. Should I try to reestablish the friendship again?

I hope he's a man of his word because time changes ALOT. I know this firsthand because I'm going through a very similar situation only difference is I have tried to reconnect , but have found my above theory to be true. In my case I think old feeling's had never been let go and because of this it caused bitterness . . .Sad , but for the most part true. I pulled away from a good friend a few years back and a few months back had gotten in contact with him. It went from hot and cold . . 2 pure HELL. A few weeks back we stopped speaking ( his doing not a choice of mine ) he never did explain why , but I assumed I knew . Although I'm what's familiar to him . .Time just like then is not on our side . . . Years later there still open wounds. So to answer your question should you try communicating with him ? Yes and no . . If you do you have to make it perfectly clear why your back around and you have to be in it to win it. If this is anything short of forever ( meaning your friendship or whatever it is you see happening ) you need to graciously be on your way. Trying sending the card . . . Ease your way back in his life . . .It may not come naturally , but if the friendship is worth it you'll figure it out.
