Long commutes are bad for marriage?

Saw and article today about how long commutes are bad for marriage.  I can't say for sure as I'm not married but I sure have a less than favorable commute that takes on average 2 hours of my day.  Frankly I'm crabby when I leave for work in the morning and pissed off when I get it.  I'm not married but it doesn't take a scientist to know that if I had a spouse, she's be dealing my  moods as well.  If i ever got married I'd have to live close to the house for both our sanity.  What do you think?
