I NEED TO KNOW THE NAME OF A MOVIE! Help please!!!?

There's this movie where this guy talks to this girl that lives in the past. He tries to save her from her evil husband. Its not the lake house! but, she has a garden that she loves with beautiful flowers. at the end of the movie the future man's ex girlfriend fins a jewelry box above the fire place, she opens it and there is a locket in there that she drops in the fireplace and that's what causes a fire in the past woman's life. i cant remember the name of it but if you have an idea of what it might be, please let me know! Thanks in advance.
