Are love stories like the Titanic a bad influence?

I used to watch movies like the Titanic when I was a teen and it made me put girls on a pedestal and I would chase them and fall so in love with them and draw pictures of them and I saw them as better then anything and deserving of my absolute love, attention and loyalty. Flash forward 20 years and now I realize that no one is as perfect as in the movies and Jack and Rose probably wouldn’t have worked out anyway even if he hadn’t drowned.
I realize now that you have to find a woman who’s as obsessed with you as you are with her and that’s even more rare than what I thought love was to begin with.
My point is that true love is probably different than the movies portray.
