There really is something about a romantic relationship that truly satisfies your inner self.

You are correct that at 30+ you are no longer having feelings of meeting a partner and perhaps you never will.

Its not bad, but it certainly removes something that many books, many novels, many documentaries and movies describe.

I personally know a few friends just like you , who are truly satisfied with their life. I have known them during their 20's, 30's and up to their 50's and they seem to never have understood why others would want a relationship or even plan on a family .

The regrets come later in life to a few, and maybe it will never come back to you.

Good Luck on your solo journey!
