Even if Betty wanted to, Duck wouldn't have an affair with Betty. Right now Don's his best supporter within the company and sleeping with Betty would be professional suicide. He may be an alchoholic but he's not suicidal.

Hi Blondeambition! I'm not sure, but, isn't the reason Duck and his wife split was because of his fooling around? And his alcoholism?
Betty would be asking for more trouble.
And, I agree with Ritt, Duck could never risk an affair with Betts at this point.

I think Duck is on his best behavior right now. However, a leopard doesn't change his spots. He's the last thing Betty needs.

Betty needs to pull herself together, shake off the June Cleaver act and learn how to function in the real world. The life of horseback riding during the day, maids and perfect McMansion ( I know that term didn't exist in 1962 ) will go when Don goes. Pulling another man into her life is not the answer.

I have no doubt that Don will move on. That final scene in the office kitchen did not show a man who was remorseful or distraught. It was a man who was sitting back, weighing his options. Who knows? Once Betty reached 40-45 and wasn't so young & cute anymore, he very likely would have traded her in for a younger woman, more befitting his professional status .... just as he did with his car.

I am a bit surprised that he did not go home ( unless he wanted to be alone to decide how to manage the situation. ) He pays for the house. Indeed every aspect of his family's lives are due to Don's income. He had every right to go home, regardless of what Betty told him to do. I'm a bit surprised that he didn't.

Don didn't go home because he cannot stand confrontation. He takes the easy way all the time with Betty to avoid a fight.

I think perhaps he is feeling regret for the dumb mistake he made with Bobbie. He really needs Betty and the kids and the perfect life. I think he will try to figure out how to appease her. Maybe a new fur coat??? (It worked the first time.)

I heard that whenever George Burns got caught cheating, Gracie never said anything, but she got a new, expensive gift shortly thereafter. I think that was just they way that generation with that kind of money handled these things. Divorce simply wasn't an option.
