I never said that all nice men are secretly needy assholes.
I am just saying that a man with no self-confidence... i.e. someone who is shy to the point of not being able to approach women, or someone who is one of these serial monogamists, who meets a girl and is IN LOVE with her within the same day... these people have no self-confidence and tend to be "Nice Guys" with quotation marks, because even though they seem like gentle loving men, secretly they are deeply confused and needy, and will treat you like a Goddess, but are keeping score the entire time. And even they don't realize it.
I don't know your guy. He might be AWESOME! But he might also just be like that because you are giving him the attention he seeks. Try backing off JUST A LITTLE, and see what happens.
