Being single and daydreaming about being in a relationship is an option, not a healthy one, but still an option.
You deserve to have it all in a relationship, everything you said, even the stuff you say you would settle to go without.
Maybe some people truly have it all? Maybe they have low expectations so they are content with what they get?
TBH, I had low expectations when I got married, but over time, I decided I deserved to have all you described. I caused the struggle by raising the bar.
As for getting a date though, there is an art to that process. You seem uncomfortable with it, insecure, over think it and talk yourself out of it.
