The problem is that similar to Jack and Jackie IOTL, the generation gap (14 v. 12) is a major marital issue- it can be minimized so as to be nearly irrelevant, but it is always there. But that was what Jack, probably correctly, diagnosed as a Freudian "father complex"- Jackie subconsciously wanting a husband similar to Black Jack. Of course, the reality is a hell of a lot more painful when Jack suddenly dumps you at a party and returns later, having been somewhere else with someone else, if you get my drift...
