That's your codependence talking to you. I struggle with the same thing but have been working on it in therapy. We've been talking a lot about healthy vs non-healthy attachment styles.
IC also said that as humans we need other people because we are social creatures. But when it becomes obsessive, that's when it gets unhealthy.
I know you've been reading Codependent No More. I would also recommend the daily reader by Melanie Beatty, it gives you something to focus on each day and is really helpful for me.
