Why am I still single?

I still don't get it.
  1. Is it my social awkwardness?
  2. Is it because I don't have a lot of friends?
  3. Is it my weight?
  4. My personality, perhaps?
  5. Does my lack of social connections make me less desirable?
  6. Am I not hiding my depression well?
  7. Is it my income?
  8. Is it because I have never been on a nice vacation and therefore am considered less cultured?
  9. Am I not the type of person you would want to introduce your loved ones to?
  10. Am I "too boring" because I don't barhop every weekend?
  11. Am I too boring in general?
  12. Does my lack of accomplishments make me less desirable?
  13. Does my shyness come off as rude or vapid?
  14. I just don't get it.
