Blast from the Past

Wow oh wow. An exboyfriend came screeching back into my life today. He sent me an email and asked me to call him. We talked for about 40 minutes on the phone. He had pushed me out of his life due to someone else he had been seeing. We were tentative friends after the breakup. He spoke quite a bit about her. I am not quite sure what he wants. I am willing to be his friend again. As for anything else...I am unsure. I really never thought I would see him again that day he drove out of my life for Chicago. He was my first LDR. I always thought much of him as a person in general. That was over two years ago. He has been back in the same state as me for about year and a half. It was at that time he quit communicating with me. He wants to see me...maybe tomorrow. I have so much nervous energy right now. My head has got that swirling , spinning feeling. Where is the switch to turn off my brain?
