I watch this a long time ago but the movie was about the man picking up the girl from an all girls school and they're the run from a man that's after the father.They act like father and daughter to other people but they're having a sexual relationship while on the road.The girl called the father was called Jack I think.At the end the girl ends up becoming pregnant and when it time to birth the baby.The father rushes to find someone to take her to the hospital.When the father goes to the hospital he finds out that she disappear.Later he finds her when's older and wearing glasses that she's married and doesn't want him around her.Towards the ending credits it shows the guy heartbroken. I think the setting was placed in the 60's.I really want to know the title of this movie because it's bugging me. Thank you for answering.
