I can’t recall a lot of details. All I recall is it has a bunch of teenagers, and one guy (who looked a bit like Ralph Macchio) was in love with this girl. She was with some guy who wasn’t too nice to her. She got pregnant, and the Macchio character helps her get an abortion. Towards the end he finds out the girl he loves is back with her boyfriend, and there is a scene of him driving away in his car. These kids were either in school together or worked together
At first I thought it was mystic pizza, but I don’t think that is it based on what I’ve seen of that movie so far.
I’m pretty sure it wasn’t Ralph Macchio himself, as his IMDB profile doesn’t mention a movie like this.
