i have too much pride to be arsed... but if u dont give a shit, then say to her why did you delete me before we go get drunk together and take you back to mine? lol. this is more of a "fuck it" message than a key to success.
example my mate had macked a girl the night before but forgot her name. had her phone number in his phone so after a few texts, asks for her facebook. she decides to play hard to get and not reply or maybe she wasn't arsed enough to give him her FB. 10 hours later no reply so i was like mate just fuck it, send "come on i need your FB quickly becuse i can't remember your name and i need see if you're hot.". she instantly replied saying "oii you're pretty eager that many messages in a row! you don't remember my name? my names blahblah, you can judge, whats yours?"
the logic in sending that text if u want to break it down is:
scenario 1: he doesnt chase her. she doesn't reply to his text. its finished its over.
scenario 2: he does chase her. he replies. he bangs her (he got a bj)
scenario 3: he does chase her. she doesn't reply. its finished... e.g. scenario 1.
but i can tell by your post you care too much so leave it. until you don't give a shit, you shouldn't do that kind of shit cos it will hurt your feelings further if she doesn't reply to your text and you'll probably do some gay shit like check your phone every hour (we all do it at one point, its cool

)
