How much does a girl cost like what is the average pay of one. Does a person spend $1000 a week, day or month on them? Is McDonalds good enough for a girl or do they want that Gordon Ramsy type shit? So I am here asking does anyone have a link or know the statistic of how much it cost. In America the cost for a parent to raise there kid is$200 000 to $300 000 from 1 to the age of 21. So they must have statistics on ho much a girlfriend cost.
