why do nice guys get treated badly? Girls will start to value more of that behavior we say as "nice" when they have few options and niceness become more of a commodity.this is the reason why young ages 14 to 26 girls, don't value gentlemanly behaves because of an abundance it when they are young.
In college, that number increases. This necessitates in her attention economy, the currency of nice suffers from inflation, which leads to her not valuing these sorts of attention or valuing less than other presents( Teasing, Challenging, Commanding, Etc .)
After college that number begins to go down, and usually by a woman's late twenties early thirties, a number of men she has exposure to on a daily basis have shrunk significantly.
This doesn't mean that a girl will only look for a guy who is nice, but she will more willing to accept that type of attention romantically.
I don't think it should be any man's aim to be nice though.
It's such a thoughtless compliment, an indicator that you are replaceable and what you give absence nuance.
If you want to do better with daughters change your focus from
" What would she like me to do to ?"-" What do I want to do ?"
