Please Help!

I believe the movie is from the 2000’s. It’s a horror movie about a woman who is tormented by a demon. At one point there is security footage of her being sexually assaulted by a invisible force in the back hallway of the market where she works. At some point she is being taken care of at a old house/cabin. When her boyfriend/husband visits they begin to kiss and she brutally bites his tongue. Towards the end of the movie a priest visits her and she greets the priest naked on the porch of the house/cabin. It’s dark and raining and I believe she proceeds to seduce and kill the priest.
