do any one know the name to a movie that keeps haunting me.

so it starts with a art auction its a sculpture made of brass(i could definitely be wrong). the bid winds down to two competitors, man and a woman. the woman won goes home to celebrate but the man follows her begging for her to sell it to her. he managed to sway her but they end up hitting it off. later on in time they go to his remote cabin where all the stuff goes down. the man is crazy seeing things clique crazy he goes through the motions to murder her. however she survives and the struggle between the two begins she gets a good head injury on him only causing his hallucinations to worsen as she get the better of him. he goes through so much psychological horror rightfully so.

I know I am probably remembering alot wrong but the way I can best describe it is a Greek comedy. the kind where you fuck around and found out hard
