Okay... did I miss something. I don't recall reading anything about your childhood. Do you think you might be giving off some "do not approach" vibe?
That does happen and guys will pick up on it and leave you alone.
Have you thought about using a dating service? I think there have been a few mentioned on this site.

To be loved is something many people wish for. To approach men sometimes comes off as being desperate and they will run. Let love turn up when you least expect it.
