I saw this movie one late night on a local channel many years ago. It was about a woman who has a romantic relationship with an older man. He doesn't want a serious relationship but he sort of keeps her around. Finally after giving up hope, she finally has the courage to let him go, realizing that the relationship will never get serious She is an artist, I believe a painter, in the end she has an opening art show and he happens to walk by and see it after some time of not seeing each other. Ahhh, I can't remember much detail but would love to know the name of this movie... anyone?

Sounds like "Shop Girl" with Steve Martin playing the older man.
