I think that there are many couples that meet and feel they "know" right from the word go. Most of these relationships fall apart over time, while some prosper and grow into something truly special. Only time will show whether these initial feelings were correct or not!
You seem to have a promising start with this girl-take care of your end of things, and hopefully in time you each will come to the realization that the other is the person that you want to team up with "for better or for worse!"
Outback Gal could have been speaking for me: I also had a wedding video story. On my sister's wedding video, our mom said to my sis and her husband: "Marriage is hard work, so be ready to go to work every day."
Anyhow, wishing the best for you!
