The "Disneyland" dad...

I was raised by good parents who instilled in my sisters and I what a man should and shouldn't do and what to expect from our future spouses. And sadly from the time I was in high school I have seen many a man be what is called a Disneyland dad, and not what my parents would define as a good spouse. If one doesn't know what a Disneyland dad is he is a man who has little to no input or takes little or no responsibility for the raising of his child or children. He is more into the having fun and giving gifts and spending only the minimum amount of time required interacting with them and then ignores them the rest of the time. The moms of these kids is left to often carry the brunt of the responsibility for making sure everyday things like getting up, going to school, feeding themselves, making sure homework is done, etc. is addressed and often these moms have little to no life beyond being that disciplinarian role. The moms of these kids usually work either full time or part time jobs and barely make ends meet and often look years older than they are. I dont know if it was the mentality of some of my parents later generation who thought it better to be their kids friend, rather than a parent to them because that would make them uncool to their kids that instilled this attitude or some other factor, but I have seen more and more of this trend with the men of my generation. I'm going to be 35 this year and have been with a very good man for 15 years and married to him for 10 of those years. He and I got married when I was several months pregnant. Now yes that is usually what would be the catalyst to the trend from my previous observations, but was not the case with him. He not only stuck with me but has been a rock and my partner though the many ups and downs of raising our daughter. Now I mentioned sisters at the beginning and yes my sisters are both married, and one of them is everything our parents taught us was a good man, but the other is all that is a Disneyland dad and more. I will admit that he has changed a little bit but not much. He also tends to backslide a great deal and my sister says that his behavior is because of his mother and her husband. But he hasn't lived with them in more than a decade when does making excuses for someone stop and they are held responsible for their own behavior. I was taught by my parents that you are responsible for yourself and can't blame anyone else for how you act. So the question is the behavior of a Disneyland dad learned at their parents knee or is it a conscious decision of behavior?
