For those of you just starting out like me, this problem will sound all too familiar... I need some advise from some old hands

Background story: I have been talking to this girl for about a week now. I am still under the seven hour mark because getting this girl alone for longer than 2 minutes has proven to be rather difficult. She came over one night for about 45 minutes and we made out. The past two nights she has said that she would come over after she stopped by her friend's place... but then never showed. We were supposed to get together on Friday night because she is leaving town Saturday evening. THE FOLLOWING IS A, WORD FOR WORD, TEXT MESSAGE CONVERSATION THAT I JUST HAD WITH HER :

HB) Really sorry about last night. I ended up leaving last night and I just
now got a phone charger because my phone has been dead... Even
though ur probley upset I will give you a call when I get back in town.

AT THIS POINT I USED A MY OWN MODIFIED VERSION "PHONE GAME" THAT I READ ON THIS SITE...

ME) "Its not a big deal but put yourself in my shoes. It seems like
everytime we are going to hang out, something more important
comes up. I could've gone out with my brother thursday night but
you told me you wanted to come over after you said hi your friend"
(SHE HAD AN OUT OF TOWN FRIEND IN THE AREA FOR THE NIGHT).
"So last night was not the first time. Blowing me off disrespects me
and my time. All I'm saying is, if you are interested in me then show
me you are interested in me."

I WAS NOT PREPARED FOR WHAT HAPPENED NEXT... EXPECTING AN APOLOGY, SHE DISARMED WHAT I HAD PREVIOUSLY SAID ABOUT WAISTING MY TIME.

HB) I have shown u that i am... this has just been a bad week ive had
friends that have come to town that i havnt seen in a while... And i
always will value my friendships over anyguy.

NOT KNOWING WHERE TO GO NEXT I DROPPED THE BALL...

ME) You should... Im not saying I should be more important than your
friends. There were just a couple of nights where I sat around
waiting on someone who never showed... But its no big deal, just give
me a call when you get into town and maybe we can hang out then.
Have fun on your trip babe, and thank you for getting back in touch
after you fixed your phone.

HB) K sounds good i really am sorry but i will give u a call when i get
back in town.

ME) K


HELP!! WHERE DID I GO WRONG... WHAT SHOULD I HAVE SAID INSTEAD OF THE MINDLESS DRIBBLE THAT CAME OUT... AND WHAT DO I SAY ON TUESDAY WHEN SHE CALLS ME BACK?
