Could a relationship work between two clingy and needy people?

Just curious. I know one couple and they're basically inseparable, kind of living in a bubble. Not sure how the dynamic works though... I reckon when it's good, its very good: 1. you have a person who understands your mindset an 2. you can learn to communicate with each other if there's issues. But the cons.. when it's bad, it's very bad.
