Women need validation in LTR through their men. I would say that that it should be given or otherwise you are emotionally unavailable and don't show enough empathy. To add, majority of women are insecure in one way or another and if you happen to jab them in the wrong spot and at the wrong time, she will think you an ass. Aside from that, misunderstanding can take place. You gotta be able to make them feel good without the ego- boost, to which you have a perfect example above, in essence, it's charm. Plus, they love when they can't figure out whether you are an assshole or a good guy.
