Sometimes you can't go back
Hey cdh... I tried the same thing. I got in touch with my college sweetheart about 6 months ago out of the blue. She became a doctor and I just happened to look her up online and send her a quick email to say hi. I always had feelings for her through the years. This was the girl of my dreams and the love of my life. I convinced her to go out to dinner with me although she had recently started dating someone. Neither of us were ever married although I am engaged. I was just curious and wanted to see if anything was there still. It was the weirdest dinner and I left the night very disappointed. This girl told me she wanted to marry me when we were in college and have my children. 15 years later there was nothing there. Nothing developed of the relationship she was in but obviously she wanted nothing to do with me because I have had to email her to prompt any contact between us. I told myself to let it go because it is more trouble than its worth. Like I said... sometimes you can never go back. If she wants to be with you all you can do is give her space. If she wants to be with you she will come around. But you can't force yourself into a relationship. Good luck.
