I know it's hard Phil, when you feel you are sitting outside the fringe of the "in crowd". I used to feel that way too and it hurts like hell.
One thing I did learn though (as I matured), that not having a boyfriend/girlfriend was NOT the end of the world. I also learned that things happen for a reason and when the time was right, I would find someone or they would find me
I found that the best thing I could do was to be a good friend to folks. From friendship came deeper relationships and lots of respect. It takes time to establish a good relationship with another person. And if a relationship with someone is meant to be more than a friendship....it will happen. Patience is key.
I also remember that while being "alone" it gave me time to work on myself. Asking questions about what I liked or disliked about myself and why. What could I do to improve? I watched other folks....what was it they were doing that attracted others to them? I learned social skills (I didn't have a lot). It was hard.....but I got through it and I know you will too.
Just think how sweet a relationship can be when it happens at the right time
Hugsss
