I love the douchebaginess of John Mayer. Okay, I also did this recently with an ex..... LOL. In my defense, he was in the UK and calling him up to break-up would have been costly.
So anyways, John Mayer just had it with Jennifer Aniston determination to get married and having babies that after chatting with her for 20 minutes, he just said, "‘I can’t take it any more,’ and hung up. Then he texted, “That’s it - the end.”
