As others have gently mentioned, the feelings you’re going through here—first growing super attached too quickly, then freaking out about a lull in contact, and finally writing this comment trying to shift some of the blame for your behavior to the other person—are textbook indications that you may have some unresolved abandonment trauma to work through. And that is something you can work on with a therapist, if you want to avoid repeating this cycle with others you click with in the future.
