When I picture honesty/vulnerability I can only see it working on a first approach, doing it within the context of an estabalished relationship seems needy.

Example:

"Hey, are you going out tonight?" - Masked intetnions, less vulnerable - plausibly deniable. "Hey, I want to see you tonight, you out?" - Honest, vulnerable

Perhaps my statements above are inccorect interpretations, please correct if you wish.

By being honest you are displaying investment, if she is not as invested you will kill the attraction?

OR is there a BASE level of attraction that has to be met? As of now it seems quite blurred.
