Nice guys women want- confident, kind to strangers, elderly, kids, funny, ambitious, genuine, relaxed, LIKES HIMSELF, if he is enamored with his partner he isn't doing it in a suffocating personality crushing way.
"Nice guys" who put women on pedestals and scare women away- pedestal placing comes from fear of losing the woman. These guys are usually very insecure and their desperation and anxiety about losing the girl comes off in what they do- flowers every day, generic pushy gift giving, bombing her with texts and DMs, time manipulation, generalizing women (she is either all women he's dated or the antithesis of the women he's dated and he lets her know, or he succumbs to that anti woman rhetoric) Everything is anxiety driven. In the end he believes the woman should be thankful for his attention. These guys usually give the aura of "give me sex you're my dream girl you're perfect" fanboy crap instead of being genuine and reacting to her interest. and if she doesn't reciprocate he lets her know "you're ugly! Women are evil! You're just one of them!" Anyone who puts someone on a pedestal in a weird obsessive way at the beginning of a relationship instantly lets me know that something may be off with him.
