Why do I want the fantasy?

Movies obviously pull on human heartstrings a lot of the time and a huge amount of the time it plays out in a sequence of events: Boy meets girl, boy, and girl fight, try to fall in love but all the obstacles or one of them gets an offer of a lifetime usually out of the city okay there's the conflict anyway but somehow almost always they get back together and live what seems to the viewer as a happily ever after. I say almost because I have seen television and movies where it doesn't work out in the end for example Blue Valentine two high school sweetheart whose marriage falls apart or Master of None as Aziz Ansari falls in love and then out of it. Though I've grown up on cliche romantic movies The Notebook so many girls would love to have that makeout scene to happen in the rain and Ryan Gosling comes in to save the day. Have I been conditioned to want something like that? Or is it just my teenage brain that thinks that love is this magical place that two people go too that I have also never seen for myself. Love to me is a fantasy, something that hasn't been tainted by a bad breakup or ex or "reality" if that's even the right word to use in this case or this blog, it's this thing that to me that  seems amazingly beautiful by how I've perceived it movies. So then does that mean that yes I want the fantasy but maybe if I had it I wouldn't like it.
