Name the film: Artist and his muse

Hi I'm looking for a film, these are the details I can remember.

Set in england on the coast. An artist is married and sees a young woman he wants to paint so invites her to his studio which is in the barn. She does some sittings for him and their relationship becomes physical.

Maybe she poses nude for him or maybe they're spotted by one of her siblings but her family find out and keep her from seeing him because he's married. But she finds out she's pregnant and eventually when she has the baby, I think it's taken to the artists house for his family to raise.

Then I can't remember anything else - I'm sure there is more! But I can't think of any  of the actors. I'm sure it was released sometime in the last 20 years from the way it was filmed.

Any help would be greatly appreciated! Thanks 😊
