When you're single, why did/do you want to be in a relationship?

As a single person, why are you looking for a relationship? I'm wondering what your main reasoning is for wanting to be in something long term.

No judgment. Just curiosity

Just to clarify I'm not talking about just wanting to be in a relationship with anyone. I am not talking about hunting for a relationship.

I am talking about actually wanting to be in a relationship with a specific person at the moment you make your decision that you want to be with this person. Why do you want to be with this person?
