NLJ. I really feel your pain. As an introvert back then, I missed many opportunities at love. I'm still introverted in a way in person, mainly because I don't like crowds.
And like Squirrel, I did find a few of the long lost girls. The main one was just before I got married. I tried and tried with her. I even was willing to adopt her son. Good kid too. I found her on FB a few years ago. Lost, divorced and living in a trailer in Kentucky. And worst of all, from a stunning near 6 foot tall and around 130 pounds, to a 500 pound girth I couldn't get my arms around.
People wonder why I don't use my name or any identifying info on the Internet. Old beaus and psychobitches its the real reason. The next best thing is a proxy .
Though I do wonder what she would have been like had she stayed with me. No matter. I have the best girl now. 25 years later, I keep the best, tease the rest.
