In my opinion, what is ridiculous is fighting over every litttle thing. She wants to go to the pumpkin patch so you cancel. Then she retaliates by demanding money and being suspicious that you have a new girlfriend (which you do, by the way). And then you get angry over that fact that she didn't call when you told her in no uncertain terms to stop calling you. How old are the two of you? 5, 8? Both of you need to grow up.
