The difference being wanted or needed in a relationship makes a profound difference in the quality of a relationship.
You don’t NEED to eat out, you could just as easily eat at home. You WANT to eat out, because sometimes you enjoy that more then eating in. It’s the same with a relationship, wanting someone is an option, a choice, where needing someone creates a dependency, and that leads to all kinds of other issues.
I would rather be wanted than needed, and i’d like the same in her.
