A film I can’t decide whether i dreamt it or not as I can’t find it anywhere!

Hi, so I vividly remember a film I saw years ago and cannot find it anywhere! I remember it was a man musician who was with a girl and they possibly wrote music together. he took credit for everything and always sang their song on his own. I remember the end scene so well, she happened to be at one of his gigs at a club and he sang this song for her and she walked out. More I think about it the more cringe it is and making me think it’s not a real film and it’s driving me insane :sweat_smile: please help. I don’t remember anyone who played in it.

A Star is Born?
