By the time the United States went to war with Afghanistan in the fall of 2001, I had made three trips to the country. I covered the fall of the Taliban in Kandahar and have been returning routinely for the past 14 years.

I just immediately connect everything to the wars I have been covering overseas, and that's not the case back home. I wrongly assumed all Americans at home were as consumed with our troops in Afghanistan as I was abroad.

It has taken me a long time to work out the function of ex-boyfriends, at least for me: how they can help you work out what you want from life and from a partner by showing you what you don't. If a man is your ex, it's better all round if he was not Mr. Right.
