Sorry to hear that, pix.
But I don't believe that's true--you just haven't found the right person yet or timing is off.
They keep saying it and I believe it's true: In order to have a healthy relationship, you have to be OK by yourself first (able to carry on independently on almost every level). The longing for a relationship when you don't have that can lead you to bad ones that you can't get out of (tragic levels of misery).
I've found that the confidence afforded by this type of independence changed my mindset which in turn changed my behavior--and I'd like to think influenced how I ultimately appeared to the world. Confidence/being comfortable in your own skin so to speak (as opposed to over confidence and bravado) is attractive even on platonic levels. And the best relationships are based on friendship first. Hang in there!
Which reminds of the news I heard from a neighbor--his childhood friend just got married for the first time at the age of 72. He never really dated anyone his whole life just met his now wife 2 years ago and boom! Just goes to show you all things are possible given time!
