It's not what women want, Its what women respond to,
Its human nature to want somthing you have to work for, so if a guy has other options lady wise he is gonna be more attractive to women then a guy who says i like you and i only have eyes for you.
Be challenging, tell her even if its not true, that your going out with another girl, e.g no i can't go out on saturday im meeting up with this cute girl but sundays good
You can be a good guy by doing this, your not a jerk your just giving her a challenge and if you don't like lying to the girl then make it a reality that your dating another girl,
Closing notes buying her flowers and being overtly nice sends the signal that i need to give you gifts for giving me the oppurtunity to date me, rather you should be saying your happy to see me and im happy to see you this is mutaul attraction. Be a good guy but NEVER be a nice boy, be dominant don't ask her where to go on dates just take her somewhere and even better tell her what you want her to wear on your date, Nice Boy=No Girls Bad Boy=Lots of girls but Challenging boy=Long Relationship p.s you'l have alot more sex in a relationship then a Bad Boy plus you won't get STDs
