People have a lot of trouble with timing their vulnerability these days especially with everything being topsy turvy in the dating marketplace. And I can't say I blame them because it can feel like a dagger right through the heart when your vulnerability isn't well-received. And even more so when you realize your values surrounding any potential relationship will be challenged to a greater extent.
Though I don't believe that most people out there are "keeping a tight score" in terms of how they appear vulnerable to others. Many people definitely want that special connection of a lifetime and they are willing to extend themselves. But are they doing it in the right way? Should they "keep score"? Should they be more reserved in their approach?
I definitely think there's a lot of breathing room for people to be much more conscientious and self-aware in their relationships before they extend very vulnerable parts of themselves.
