Like I said, I didn't even bother to watch the video.
From myself, a man who previously had lived in the world in a big sin city, came back to the Faith late in life, married, and now a Father of many girls:
The steps of courtship for marriage:
1) Make friends with the father, real friendship, not a deceitful friendship to gain his daughter. Help him at work or around the house. If you are not a Catholic, you will realize from him that you have to do the same with God, "Make friends with the God, real friendship, not a deceitful friendship to gain this daughter", by becoming a real Catholic.
When you have done that, without losing it with the daughter and making a fool of yourself, then maybe, you'll stand a chance of being invited over for dinner or a day in the park to be with the family.
It's a long way before you'll be able to show your interest. Catholic marriage is forever, it will be a difficult road if you are both fertile and have many children. Courtship is a long process to weed out those that are not worthy.
