Women respond viscerally in their vagina area to unpredictability, mixed signals, danger, and drama in spite of their best efforts to convince themselves otherwise. Managing your relationship in such a way that she is left with a constant, gnawing feeling of impending doom will do more for your cause than all the Valentine’s Day cards and expertly performed tongue love in the world.

Her love for you will blossom under these conditions. Result: she works harder to please you.
The key for the man is to adopt a posture of blase emotional distance alternated with loving tenderness. Too much of either and she’ll run off.
