ive learned this the hard way over many many women


1:they are leaving replying a set time to not come across as too keen (when they are)
2:you are just not THAT important to them, they have other guys , you are just a filler, or somthing they think wont go anywhere
3:they are genuinely busy-- with their career-- family issues

best way to deal with ALL those at once and WIN
dont let it bother you and put it to the back of your mind - reply when you want to reply, wether its straight away or not

but i hear you say 'oh im really into this girl' OR 'oh im not that arsed about her but its bugging me'

the best way to handle that is to have MULTIPLE girls on the go at the same time-- i recommend about 3 or 4

it works!
