$25 Bounty: 1980s movie ; family drama

I’m trying to find the name of a movie from the 1980s. While I don’t remember many details, the few that I know, hopefully can jar someone’s memory. It’s a movie about a female actress. I remember in one scene, she tells her young daughter, that while she may kiss another man on stage, her father is the man she truly loves. At some point, the actress and her husband, separate. In the final scene in the movie, the girl, who was the young girl, is now a full grown woman, and is with her father as he dies, and she relays to him that no matter what happens that she knew her mother truly loved him.

Help is appreciated. I’ve been trying to find the name of this movie for years. I saw it as a young boy and never forgot it.
