One can only imagine what she did to Aron to make his hit the road.
Just be herself, apparently.
I read her column every Sunday, probably because something about her irritates and fascinates me at the same time. If I recall correctly, Aaron started out as a friend, and over a long period of time they slowly realized that they loved each other and really wanted to be together. For several columns everything was bliss. Then they hit a bump in the road: politics.
Turned out Aaron was a Republican, and he (gasp!) supported the war. She wrote a column about it in which she moaned about how awful it was to have a mate who wasn't as politically perfect as she was. They began to argue. She sent him a series of emails containing "facts" about the war (probably gleaned from Dummycrats Underground). One of these charming screeds had in the subject line: "Read this, warmonger!" He stood up for himself, which apparently infuriated her even more. She ended that column with the observation that her parents were coming to town the following week to meet him, and that they were even more liberal than she was. She wondered how dinner would be with three liberals and one conservative.
The next column, suddenly Aaron was gone. He had dumped her and she was devastated. She didn't go into too much detail about his reasons, but I have my suspicions. I think Aaron looked ahead to that dinner with her folks and realized that he would have to contend with Bush-bashing from all sides at once, all night long. And if he went ahead and married this girl, he could look forward to more of the same at every family gathering for years to come. When you factor her existing flakiness into the equation it looks like Aaron did the smart thing when he bailed.
