DUDE how many frickin times are you going to apologize and tell her that "This is the last time I will be talking to you"
You did it in an e-mail... didn't you do it in a text message? And now a phone call.. GIVE IT A REST - she doesn't need to know that this is the last time you will be talking to her because she dumped you dude, that comes along with it! Have some dignity and some self-respect.. stop....contacting.....HER!
