I'm not who you were replying to, but I agree and disagree with your comment.
I'm not saying someone can't be happy single. But society makes it hard to be when the world revolves around relationships, being a virgin is used as an insult, etc.
But I do agree with you that not everyone needs to have a partner. I don't see myself ever getting into a relationship, and to some extent I'm often close to making peace with that, until I see a post, a comment, a video, etc, that makes me feel inferior due to it.
I do appreciate, though, the fact that you admit not everyone needs to have a relationship and that not everyone will have one. I'll take this approach every day of the week over the "Naaah, I'm sure you will be in a relationship soon cause everyone does!", followed by moving the goalpost (it's always "soon" regardless of how many years have passed).
