If I know women, which I do, they always think long, hard and rationally about decisions involved in emotions. So many girls I know will brood over someone's ask for a relationship for weeks -- often times months -- weighing the pros and cons and conducting large-scale data analysis about the benefits of this relationship. Eventually once all the data is processed a decision is made. Honestly this is pretty standard stuff for a girl to put you in this "wait and see" zone and it almost always has positive results. Hopefully the Excel spreadsheets are in his favor.
