Are fully integrated mentally healthy people less attractive?

I get that's controversial and abstract, but hear me out.

If someone has done a lot of work on themselves and they have slayed their demons and have no need of anyone else because they have absolute faith in their ability to be happy single, what does romance offer? Love is absolutely brutal, so why would they give up no problems for problems?

I come up with this because I have have this stinging sense on dates that many women just aren't interested in anything I'm selling, and I'm not sure exactly what I could be selling they would want. They have everything they require, seemingly, and not feeling wanted by the other person makes the other person unattractive.

EDIT: I have worded this badly. My core question should have been "Women, do you find that having a lot of dating experiences and knowing what you want and will not put up with has diminished your interest in finding something or made it harder?"
