I theorize that he's a romantic and expects far too much out of his wife and out of marriage in general. It's possible to spend the rest of your life with someone who does things that annoy you.
I suspect they agreed it looked better for him to say he asked for the divorce.
Rush is a big-picture guy. I theorize that he's in love with love. When he and Marta first married, I could barely stand all the syrupy "hi sweetie" stuff, and her calls to him while he was on the air. That's high school infatuation stuff. Rush was 43 years old, had changed a country with his ideology, and was gurgling over a female like a love-struck teenager. That's why I say he's an emotional wreck when it comes to women. He's stuck with an adolescent view of them.

Well, I wouldn't know. I'm lucky enough to have married a woman whose major gripe in life, after 27 years, is that she doesn't have enough time or space to plant more rose bushes.
Or maybe he's just married to his job; a lot of men are like that, and more often now, women too.
Although, by the 3rd time around, why even bother to get married? Anyone who has married and divorced that many times is definately not marriage material and anyone who marries a thrice divorced individuals is just being stupid.
How about a three strikes and you're out law for marriage? People shouldn't be allowed to get married that many freaking times.
