This one may be tough. I’m piecing it together from memories over 25 years ago when I saw this movie on TV as a kid one afternoon. It likely is a 70’s or 80’s movie.
It’s about a blonde woman, middle-aged who seems to walk everywhere; even carrying her suitcase long distances to meet and visit people. It seems like she has an aversion to driving and/or riding in cars; maybe even afraid to get in cars but I can’t remember the reasoning.
In the ending scene, she’s having an argument one night with a man (I think) and the man storms out, gets in a car and starts to drive away. The woman picks up her suitcase and starts walking after him. One of her friends (another guy I think) tries to stop her and calls her back but she just keeps going down the street with her suitcase in hand into the night. The movie then ends.
The movie has a pretty serious tone to it. Kind of a depressing ending too.
